What is Tungsten Disulfide Powder?

What is it? Tungsten Disulfide Powder ? Tungsten dioxide is an organic compound that has a molecular structure of WS2 as well as a molecularweight of 247.97. It is a fine powder or crystal with a gray metallic appearance. It belongs in the hexagonal system of crystals. Tungstenite is a natural mineral. This layer structure is simple to dissociate with similar lubricating qualities to graphite. Useful as a Lubricant in Aerosols.
Tungsten Disulfide Powder: The Main Features
Tungsten dioxide is a compound made of tungsten, sulfur and has a chemical formula WS2 as well as a molecular mass of 247.97. It is a black-gray, powder. It looks like tungstenite in the natural world and is a dark gray crystalline solid. Its relative density is 7.10. The relative density is 7.510. It is insoluble in hydrochloric acids and alkali, except for the mixture of hydrofluoric acid with concentrated nitric. Soluble in molten alkali, insoluble in alcohol. Density 7.6g*cm-3. It has a reducibility, which allows it to react with hot concentrated sulfic acid, nitric and other strong oxygenants. It is broken down into tungsten (or sulfur) when heated to 1250 under vacuum. To eliminate excess sulfur, the mixture is heated to 900°C in a stream of pure nitrogen. The remaining substance is tungsten dioxide.

Tungsten Disulfide Pulver’s applications
Useful as a lubricant. Higher performance than molybdenum sulfide, lower friction coefficient, and higher compressive strengths. It can be used in conjunction with other lubricants for high temperatures, high pressure, high speeds, high loads, and equipment that runs in chemically active media. Combining other materials with forging and stamping oils can extend the life of the die, and increase the quality of the finished product. Filler material formulated with polytetrafluoroethylene and nylon for self-lubricating parts.
