Brief Introduction toTungsten Disulfide
Product name: Tungsten Disulfide
Description of Tungsten Disulfide
Tungsten disulfide (Tungsten disulfide) is an inorganic compound with a molecular formula of WS2 and a molecular weight of 247.97. It is gray fine crystal or powder with metallic luster, belonging to hexagonal crystal system, semiconducting and diamagnetic. The natural mineral is tungstenite. Layered structure, easy to dissociate, has similar lubricating properties to graphite. Use as a lubricant, e.g. for aerosols

Tungsten disulfide is a compound of tungsten and sulfur, chemical formula WS2, molecular weight 247.97, the state is black gray powder, it appears as tungstenite in nature, and it is dark gray orthorhombic crystalline solid. The relative density is 7.510. Slightly soluble in cold water, soluble in hot water [2] . Insoluble in hydrochloric acid and alkali (except the mixture of concentrated nitric acid and hydrofluoric acid). Soluble in molten alkali, insoluble in alcohol. The density is 7.6g·cm-3. Reducing, it can react with hot concentrated sulfuric acid, nitric acid, aqua regia and other strong oxidants, and can be converted into WO3 when heated in air or oxygen. [1] It decomposes into tungsten and sulfur when heated to 1250°C in vacuum. In the dry pure nitrogen flow, heat the mixture of tungsten trisulfide and sulfur to 900°C to sublimate the excess sulfur, and the residue is tungsten disulfide.
Application of Tungsten Disulfide
What is Tungsten Disulfide used for? Often mixed with graphite fluoride, graphite and molybdenum disulfide as a high-temperature lubricant, the boron nitride powder dispersed in oil or water can be used as a lubricant for drawing or pressing the forming, or as a lubricant for the sliding parts of the high-temperature furnace, and the sintering body of boron nitride can be used as a material for bearings and sliding parts with self-lubricating properties. Diamond boron nitride is a new high-temperature resistant superhard material for making drills, grinding tools, and cutting tools.
The specific uses of Tungsten Disulfide are as follows:
1. Metal forming release agent and lubricant for metal drawing.
2. Special electrolytic and resistance materials at high temperatures.
3. High-temperature solid lubricant, extrusion and anti-wear additives, the production of ceramic composite material additives, refractory materials and antioxidant additives, especially anti-molten metal corrosion occasions, heat-enhancing additives, high-temperature-resistant insulation materials.
4. Heat sealing desiccant of the transistor and polymer additives such as plastic resin.
5. Suppressed into various shapes of boron nitride products, can be used as high temperature, high pressure, insulation, and heat dissipation components.
6. Thermal shielding materials in aerospace.
7. With the participation of a catalyst, cubic boron nitride can be converted by high temperature and high-pressure treatment.
8. Structural material of the atomic reactor.
9. Insulator of high voltage, high-frequency electric, and plasma arc.
10. Packaging materials that prevent neutron radiation.
11. Superhard materials made of boron nitride processing can be made into high-speed cutting tools and drills for geological exploration and oil drilling.
12. The Metallurgical separation ring is used for continuous casting steel, the amorphous iron flow groove mouth, and the mold release agent used for continuous casting aluminum (various optical glass film release agents).
13. Make the evaporation boat of various capacitor film aluminum plating, imaging tube aluminum plating, display aluminum plating, etc.
14. All kinds of laser anti-counterfeiting aluminum plating, trademark hot stamping materials, all kinds of cigarette labels, beer labels, packaging boxes, cigarette packaging boxes with aluminum plating, and so on.
15. Cosmetics are used in lipstick fillers, non-toxic, lubricating, and shiny.
