How is Zinc Sulfide ZnS Powder Produced?
Zinc sulfide is usually made from waste materials for other purposes. Typical sources include smelters, slag, and pickling liquor. It is also a by-product of ammonia synthesis from methane, where zinc oxide is used to remove hydrogen sulfide impurities in natural gas.
 
What is zinc sulfide used for? 
The most common use of ZnS is used as a pigment for paints, plastics, and rubber. Lithopone, a mixture of ZnS and barium sulfate (BaSO4), is a widely used pigment for low-gloss paints. ZnS is phosphorescent, which makes it useful for several electronic and decorative applications.
High-purity crystal zinc sulfide powder is an important basic material widely used in high-tech fields such as civil, military, aerospace, and other high-tech fields. It is also an extremely important window material for medium-long-wave far-infrared precision guidance and far-infrared imaging, especially in national defense. Military and other cutting-edge technology fields. The applications of Zinc Sulfide are as following:
Luminescent material
Zinc sulfide, coupled with a small amount of suitable activator, has strong phosphorescence and is currently used in various applications from cathode ray tubes to X-ray screens to emit light in dark products. When silver is used as the activator, the resulting color is bright blue with a maximum of 450 nm. The use of manganese produces an orange-red color of about 590 nm. Copper can glow for a long time and has the familiar dark green glow effect. Copper-doped zinc sulfide (“ZnS + Cu”) is also used in electroluminescent panels. It also exhibits phosphorescence due to impurities under blue or ultraviolet light irradiation.
Optical materials
Zinc sulfide is also used as an infrared optical material, transmitting from visible light wavelengths to just over 12 microns. It can be used as a flat surface as an optical window or shaped as a lens. It is made of hydrogen sulfide gas and zinc vapor to make microchips and sold as FLIR grade (front looking infrared), in which zinc sulfide is in creamy yellow, opaque form. When hot isostatic pressing (HIPed), the material can be converted into a transparent form of water, called Cleartran (trademark). Early commercial forms were sold as Iran-2, but this name is now obsolete.
Pigment
Zinc sulfide is a common pigment, sometimes called statolith. When combined with barium sulfate, zinc sulfide forms lithopone.
Catalyst
The fine ZnS powder is an effective photocatalyst, generating hydrogen from water when illuminated. Sulfur vacancies can be introduced into ZnS during the synthesis process. This gradually turns white to yellow ZnS into a brown powder and enhances photocatalytic activity through enhanced light absorption.

Feature of Zinc Sulfide ZnS Powder:

Indium Tin Oxide ITO Powder

About Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is a ternary composition of different ratios of indium, tin and oxygen. According to the oxygen content, it can be described as ceramic or alloy. Usually encountered indium tin oxide as an oxygen-saturated composition, its formulation is 74% In, 18% O2 and 8% Sn by weight. Oxygen-saturated compositions are so typical that unsaturated compositions are referred to as oxygen-deficient ITO. The thin layer is transparent and colorless, and the bulk is a pale yellow to gray. In the infrared region of the spectrum, it acts like a metal mirror.
 
Indium tin oxide is one of the most widely used transparent conductive oxides because of its electrical conductivity and optical transparency and the ease with which it is deposited as a thin film. As with all transparent conductive films, a compromise must be made between conductivity and transparency, because increasing the thickness and increasing the concentration of charge carriers will increase the conductivity of the film, but will reduce its transparency.
 
Indium tin oxide films are most commonly deposited on the surface by physical vapor deposition. Usually, electron beam evaporation or a series of sputtering deposition techniques are used.
 
ITO is a mixed oxide of indium and tin. Depending on the composition, its melting point is in the range of 1526-1926°C. The composition of the most commonly used material is ca In4Sn. This material is an n-type semiconductor with a large bandgap of about 4 eV. ITO is transparent to visible light and has relatively high electrical conductivity. These features have great advantages in touch screen applications such as mobile phones. Feel free to send an inquiry to get the latest price if you would like to buy Indium Tin Oxide ITO Powder in bulk.

Performance of Indium Tin Oxide ITO Powder:

Chemically, ITO is the abbreviation of Indium Tin Oxides.
As a nano-indium tin metal oxide, it has good conductivity and transparency and can cut off harmful electronic radiation, ultraviolet rays and far-infrared rays. Therefore, indium tin oxide is usually sprayed on glass, plastic and electronic display screens, used as a transparent conductive film, while reducing harmful electronic radiation and ultraviolet and infrared.
In the oxide conductive film, the Sn-doped In2O3 (ITO) film has the highest transmittance and the best conductive performance, and it is easy to etch fine patterns in the acid solution, of which the light transmittance is more than 90%. The transmittance and resistance of ITO are controlled by the ratio of In2O3 and SnO2, usually SnO2:In2O3=1:9.

How is Indium Tin Oxide ITO Powder produced?
The ITO powder usually adopts the following preparation method: respectively oxidizing metal indium and metal tin to obtain indium oxide powder and tin oxide powder and then mixing and dispersing the indium oxide powder and tin oxide powder. In this method, it is difficult to completely synchronize the control conditions such as metal indium and metal tin as the basic raw material, such as the dissolution rate, dissolution temperature, neutralization pH value, neutralization temperature, and stirring speed, so the prepared indium oxide powder, The particle size deviation of tin oxide powder is large, which affects the quality of ITO film. In order to solve the problem of the uniformity of ITO powder, the co-precipitation method is also used to produce ITO powder. This method uses nitric acid to dissolve metal indium and metal tin, and then mix the resulting indium nitrate and tin nitrate according to the ratio, and then use ammonia to co-precipitate. Precipitation to obtain co-precipitated hydroxide, and finally, calcination to obtain indium tin oxide.
 
Applications of Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is an optoelectronic material that has been widely used in research and industry. ITO can be used in many applications, such as flat panel displays, smart windows, polymer-based electronics, thin-film photovoltaic products, glass doors for supermarket freezers and architectural windows. Also, the ITO film used for the glass substrate helps the glass window to save energy.
 
The ITO green belt is used to produce electroluminescent, fully functional and fully flexible lamps. Besides, the ITO film is mainly used as an anti-reflective coating and is used in liquid crystal displays (LCD) and electroluminescence, where the film is used as a conductive transparent electrode.
 
ITO is commonly used to make transparent conductive coatings for displays (such as liquid crystal displays, OLED displays, plasma displays, touch panels, and electronic ink applications). ITO film is also used for organic light-emitting diodes, solar cells, antistatic coatings and EMI shielding. In organic light-emitting diodes, ITO is used as the anode (hole injection layer).
 
The ITO film deposited on the windshield is used to defrost the windshield of the aircraft. Heat is generated by applying a voltage to the film.
 
ITO is also used in various optical coatings, the most famous being infrared reflective coatings (hot mirrors) used in automobiles and sodium vapor lamp glass. Other uses include gas sensors, anti-reflective coatings, electrowetting on dielectrics, and Bragg reflectors for VCSEL lasers. ITO is also used as an infrared reflector for low emissivity window panes. Starting with the Kodak DCS 520, later Kodak DCS cameras also used ITO as a sensor coating to enhance the response of the blue channel.
 
ITO thin film strain gauges can operate at temperatures up to 1400°C and can be used in harsh environments such as gas turbines, jet engines and rocket engines.

Tungsten Disulfide WS2 Powder CAS 12138-09-9

About Tungsten Disulfide WS2:
Tungsten disulfide is an inorganic compound composed of tungsten and sulfur, with the chemical formula WS2. This compound is part of a group of materials called transition metal dihalides. It naturally appears as a rare tungsten ore. This material is part of certain catalysts used for hydrodesulfurization and hydrodenitrogenation.
WS2 uses a layered structure similar to MoS2 or the same type of MoS2, instead of a coordination sphere with W atoms (instead of molybdenum atoms) in a triangular prism. Due to this layered structure, WS2 formed inorganic nanotubes, which were discovered after heating a thin sample of WS2 in 1992.
Most of the WS2 forms dark gray hexagonal crystals with a layered structure. Like the closely related MoS2, it has the characteristics of a dry lubricant.
Although people have long believed that WS2 is relatively stable in ambient air, recent reports on single-layer WS2 oxidation in the environment have found that this is not the case. WS2 is converted to tungsten oxide in a single layer form by a photooxidation reaction fairly quickly (within a few days in ambient light and atmosphere). The oxidation process includes visible wavelength light easily absorbed by the single-layer WS2 (
WS2 is also attacked by a mixture of nitric acid and hydrofluoric acid. When heated in an oxygen-containing atmosphere, WS2 is converted to tungsten trioxide. When heated in the absence of oxygen, WS2 will not melt but will decompose into tungsten and sulfur, but the decomposition temperature is only 1250°C.
Historically, the separation of monolayer WS2 used a chemical exfoliation method, that is, inserting lithium from n-butyl lithium (in hexane), and then stripping the inserted Li compound by ultrasonic treatment in water. WS2 is also shed by treatment with various reagents such as chlorosulfonic acid and lithium halide. Feel free to send an inquiry to get the latest price if you would like to buy tungsten disulfide WS2 powder in bulk.

How is Tungsten Disulfide WS2 produced?
1. Roasting decomposition method:
Tungstic acid reacts with ammonia water under stirring at 57-60°C for 3 hours, and the heat preservation naturally settles for more than 16 hours. The generated ammonium tungstate reacts with hydrogen sulfide gas to generate ammonium tetrathiotungstate after high-temperature roasting and decomposition into tungsten disulfide.
H2WO4+2NH3·H2O→(NH4)2WO4+2H2O
(NH4)2WO4+4H2S→(NH4)2WS4+4H2O
2(NH4)2WS4+3O2→2WS2+4NH3+2S+2SO2+H2O
2. Tungsten reacts very slowly with liquid sulfur. WS2 can be formed by passing sulfur vapor to red hot tungsten. Tungsten is mixed with stoichiometric sulfur bloom and reacted in a nitrogen atmosphere at 800°C for 24 hours to form WS2, such as reacting at 6MPa and 1800°C to form orthorhombic WS2.
3. Using ammonium tetrathiotungstate as the raw material, heating and decomposing the ammonium tetrathiotungstate under the condition of isolating the air, the temperature rises from room temperature to 700-1200℃ with a temperature gradient of 100-200℃/hour during heating. After being kept at this temperature for 24 to 48 hours, it is then reduced to room temperature with a temperature gradient of 30 to 110°C/hour, and the material is discharged and crushed.
The preparation method of ultrafine scaly crystal tungsten disulfide used for lubricants has simple process equipment, does not pollute the environment, and is safe and reliable in operation, and can produce tungsten disulfide with stable quality, high purity, and ultrafine crystal structure of hexagonal crystal system.

Applications of Tungsten Disulfide WS2:
Tungsten disulfide (WS2) or tungsten disulfide is a very smooth dry film friction coating. The friction coefficient of WS2 is extremely low, 0.03, which is lower than PTFE, graphite or molybdenum disulfide (MoS2).

Vanadium Nitride VN Powder CAS 24646-85-3

About Vanadium Nitride VN Powder :
Vanadium nitride VN is a compound of vanadium and nitrogen. Vanadium nitride, also known as vanadium-nitrogen alloy, is a new type of alloy additive that can replace ferrovanadium in the production of micro-alloyed steel. It has two crystal structures: one is V3N, a hexagonal crystal structure, with extremely high hardness, with a tiny hardness of about 1900HV and an undetectable melting point; the other is VN, with a face-centered cubic crystal structure, with a tiny hardness of about 1520HV and a melting point of 2360 degrees.
 
Vanadium nitride is formed during the nitriding process of steel and increases wear resistance. In the nitriding process, another phase V2N (also called vanadium nitride) can be formed together with VN. VN has a cubic rock salt structure.

Graphite, the Most Useful Mineral with Extreme Features and Users

What’s graphite? Graphite A dark grey to black metallic mineral that is very soft and shiny with a distinctive, greasy sensation. Graphite, one of the Earth’s softest minerals will leave marks on paper. This is why graphite pencils are so popular. Graphite can be found as a natural form of crystalline Carbon. It is an elemental mineral and metamorphic rock. Graphite, an extreme mineral, is a good example. It is extremely soft, has very little pressure for splitting, and its specific gravity is low. However, its heat resistance is exceptional and it’s inert when coming into contact with other materials. This makes it a popular choice in manufacturing and metallurgy.

Geological occurrence

Graphite can be described as a form of carbon that forms when carbon is exposed to pressure and heat in the crust and uppermantle. For graphite to be produced, it needs to be heated at 750 degrees Celsius and pressured at 75,000 psi. These conditions correspond with granite metamorphic stages. Graphite – Graphite crystals found in marble pieces from Mont-Tremblant Les Laurentides RCM Quebec, Canada. This specimen measures about three inches (7.6cm).

Graphite due to regional deterioration (flaky graphite)

The majority of graphite found on the Earth’s surface today comes from the converging plates boundary. This is the place where the pressure and heat of regional metamorphism causes organic-rich limestone and shale to melt. It produces schist, marble, and gneiss that contain small crystals and graphite flake. These rocks may be extracted from the ground if they have a high concentration of graphite. They can then be crushed into smaller particles which can produce graphite flakes. It is also known as “flakegraphite”. Natural flake graphite looks almost like fishphosphate

Graphite from metamorphic coal mines (“amorphous”)

The metamorphism and formation of some graphite from coal seams is a key factor. Most of the organic material in coal is made up carbon, oxygen hydrogen, nitrogen, sulfur and other elements. Heat from metamorphism causes the destruction of organic molecules in coal, and it volatilizes sulfur, hydrogen, nitrogen, and oxygen. It is possible to crystallize mineral graphite from the almost pure carbon materials. These graphite “joints” correspond to the original coal layers. Amorphous graphite is the name given to this material when mined. It is not correct to use the term “amorphous graphite” because it has a crystal-like structure. The appearance of the material in mines is very similar to that of coal. It does not have bright and dark bands.

Graphite from igneous rocks or meteorites

A tiny amount of graphite can be found as the main mineral within igneous rocks. This mineral is found in tiny quantities in basalt flow, syenite and other minerals. Also, it is known to form in pegmatite. Some meteorites have small amounts of graphite. These types of graphite do not have economic value.

Graphite & diamond

Graphite, and diamond, are two forms of carbon. Under extreme pressure and heat, diamonds can be formed in the mantle. At lower temperatures and under higher pressures, most graphite that is found close to the earth’s surface was formed within the crust. Although the compositions of graphite, diamond and other forms are similar, the structures they form are quite distinct. In graphite, carbon atoms are linked in a hexagonal grid to create an atom-thick sheet. This thin plate is not connected well and will slide or split against each other if it bears a slight force. Graphite is extremely soft, has perfect cleavage, and is very smooth. Instead, each carbon atom in the diamond is connected to create a framework. The three-dimensional network is formed by each carbon atom being connected with the four remaining carbon atoms. Each carbon atom has strong covalent bond to create a framework. The arrangement holds diamond’s atoms securely, which makes it a highly hard material.

Synthetic Graphite

The heating of high-carbon materials, such as petroleum coke (and coal tar pitch), to 2500-3000 Celsius creates synthetic graphite. These high temperatures cause the destruction or extermination of many volatile compounds and metals from the raw materials. The remainder of graphite forms a sheet-like structure. If you need to use synthetic graphite in high-quality products, it can surpass 99% carbon purity.

Applications for Graphite

Graphite is used for a wide variety of purposes, some almost incompatible. A carbon allotrope and the softest mineral in the world, graphite can be used as a lubricant. Writing instruments, lubricants and other uses include graphene. A single-atom thick graphene cylinder can be formed. It is super strong and ideal for use in sports equipment. Graphite is a non-metal that behaves just like metal. It can conduct electricity but also resists high temperatures. Graphite forms a thin film when it reacts with water vapor. This helps to reduce friction and create a layer of graphite on the surface. It is a suspended oil component that reduces friction between moving parts. Graphite may be used in lubricants at up to 787 Celsius (1.450 Fahrenheit) or as a release agent up to 1 399 Celsius (2,399 Fahrenheit). Graphite, which can withstand very high temperatures without having to undergo chemical changes, is a popular refractory metal. It can be used to make steel, glass and iron. Also, it can be used as an asbestos replacement for car brake pads. Lithium ion battery have graphite and lithium anodes. The graphite anode will be surrounded by positively charged lithiumions as they are charged. While lithium anodes may be used to make more powerful batteries than they are, it will expand a lot during charging. As time passes, the cathode surface cracks, which allows lithium ions to escape. They then form dendrites, which can shorten the life of your battery. Tungstenmolybdenummetals (aka. Tungstenmolybdenummetals is an advanced material. With over 12 years’ experience, Tungstenmolybdenummetals is an established global supplier of chemical material. High purity and fine particles are the hallmarks of our graphite granule. Lower?
