What is Tungsten Disulfide?
Tungsten disulfide (WS2, Tungsten Disulfide) is a low-dimensional transition metal sulfide with a layered structure similar to that of graphene. It is widely used in optoelectronics, lubrication, and energy storage due to its good mechanical, thermal, optical and electrical reasons. , medical and other fields.
Physical Properties of Tungsten Disulfide:
Appearance is black gray powder, density 7.6g/cm3, slightly soluble in cold water, soluble in hot water, insoluble in inorganic acids, alkalis and alcohols except concentrated nitric acid and hydrofluoric acid mixture, but soluble in molten alkali. Because W in WS2 is in an intermediate valence state, it has strong reducing and oxidizing properties, and is easy to react with hot concentrated sulfuric acid, nitric acid, aqua regia and other strong oxidants to produce WO3 or WS3; in addition, heated to 1250 in vacuum ℃ will decompose into tungsten and sulfur.
Tungsten Disulfide Crystal Structure:
From a microscopic point of view, WS2 is a lamellar hollow sphere with a hexagonal crystal system. S-W-S molecular clusters form a hexagonal network on its surface, and the layers are connected by van der Waals forces and the layers are linked by W-S covalent bonds.
Preparation Method Of Tungsten Disulfide:
1. Roasting decomposition method: First react tungstic acid with ammonia water to generate ammonium tungstate, and then react with hydrogen sulfide gas to generate ammonium tetrathiotungstate, which is roasted at high temperature and decomposed into WS2.
2. Direct synthesis method: WS2 can be formed by passing sulfur vapor into red-hot tungsten.
In addition to the above two methods, there are hydrothermal synthesis method, high temperature solid phase synthesis method and so on.
Tungsten Disulfide Use:
1. As a lubricant, it is suitable for use in places with harsh working environments, mainly because tungsten disulfide has a low coefficient of friction, good compression resistance and oxidation resistance.
2. Used as energy storage electrode material. WS2 can significantly improve the electrochemical performance and safety of electrode materials due to its good electron transport rate and thermochemical stability.
3. It is used as a petroleum catalyst, because it has the characteristics of good cracking performance, stable and reliable catalytic activity, and long service life.
Tungsten Disulfide Packaging:
25kg or 50kg net weight, packed in double-layer polyethylene plastic bags inside, and plastic drums/iron drums as outer packaging; vacuum packaging or other net weight requirements, or the order weight is less than the standard packaging specifications, customized according to the actual situation; conventional packaging is Product name + batch number and other neutral text printing//writing, if you need personalized content, you can also customize.

What Is Spherical Tungsten Powder?
Spherical tungsten powder is a kind of metal tungsten powder with spherical powder shape. It is the raw material for preparing tungsten processing materials, tungsten alloys and tungsten products.
Physical and Chemical Properties of Spherical Tungsten Powder:
Appearance is gray-black fine powder, melting point is about 3400 ℃, boiling point is about 5555 ℃, density is 19.3g/cm3 equivalent to gold, hardness is like diamond, reducibility is strong, purity is as high as 99.9%, bulk density is 11.6g/cm3, tapped Density 12.5g/cm3. Under normal circumstances, the higher the degree of spheroidization, the smaller the particle size and the narrower the particle size distribution of the powder, the better the powder flowability and the higher the bulk density.
Production Method of Spherical Tungsten Powder:
1) The product can be obtained by the secondary oxidation and re-reduction technology of tungsten powder.
2) Use the granulation and sintering method to produce spherical powder.
3) It can be prepared by rotating electrode DC arc plasma method.
4) Preparation of large particle powder from tungsten hexafluoride by vapor deposition method.
5) The ordinary tungsten powder is spheroidized and air-cooled with an inductively coupled plasma torch to obtain the product.
Spherical Tungsten Powder Application:
Spherical tungsten powder is the main raw material for the production of tungsten alloy, tungsten material and cemented carbide. W powder can be mixed with other metal powders to make tungsten alloy; W powder can be processed into tungsten materials such as tungsten rods, tungsten wires and tungsten bars; W powder can be made into tungsten carbide powder after carbon treatment, and tungsten carbide powder can be made into Cemented carbide tools such as milling cutters, drills and dies.
Spherical Tungsten Powder Packaging:
25kg or 50kg net weight, packed in double-layer polyethylene plastic bags inside, and plastic drums/iron drums as outer packaging; vacuum packaging or other net weight requirements, or the order weight is less than the standard packaging specifications, customized according to the actual situation; conventional packaging is Product name + batch number and other neutral text printing//writing, if you need personalized content, you can also customize.

What Is Spherical Tungsten Powder?
Spherical tungsten powder is a kind of metal tungsten powder with spherical powder shape. It is the raw material for preparing tungsten processing materials, tungsten alloys and tungsten products.
Physical and Chemical Properties of Spherical Tungsten Powder:
Appearance is gray-black fine powder, melting point is about 3400 ℃, boiling point is about 5555 ℃, density is 19.3g/cm3 equivalent to gold, hardness is like diamond, reducibility is strong, purity is as high as 99.9%, bulk density is 11.6g/cm3, tapped Density 12.5g/cm3. Under normal circumstances, the higher the degree of spheroidization, the smaller the particle size and the narrower the particle size distribution of the powder, the better the powder flowability and the higher the bulk density.
Production Method of Spherical Tungsten Powder:
1) The product can be obtained by the secondary oxidation and re-reduction technology of tungsten powder.
2) Use the granulation and sintering method to produce spherical powder.
3) It can be prepared by rotating electrode DC arc plasma method.
4) Preparation of large particle powder from tungsten hexafluoride by vapor deposition method.
5) The ordinary tungsten powder is spheroidized and air-cooled with an inductively coupled plasma torch to obtain the product.
Spherical Tungsten Powder Application:
Spherical tungsten powder is the main raw material for the production of tungsten alloy, tungsten material and cemented carbide. W powder can be mixed with other metal powders to make tungsten alloy; W powder can be processed into tungsten materials such as tungsten rods, tungsten wires and tungsten bars; W powder can be made into tungsten carbide powder after carbon treatment, and tungsten carbide powder can be made into Cemented carbide tools such as milling cutters, drills and dies.
Spherical Tungsten Powder Packaging:
25kg or 50kg net weight, packed in double-layer polyethylene plastic bags inside, and plastic drums/iron drums as outer packaging; vacuum packaging or other net weight requirements, or the order weight is less than the standard packaging specifications, customized according to the actual situation; conventional packaging is Product name + batch number and other neutral text printing//writing, if you need personalized content, you can also customize.
