Tungsten disulfide is a compound of tungsten and sulfur with chemical formula WS2 and molecular weight of 247.97. It is a black-gray powder. It appears as tungstenite in nature and is a dark gray orthorhombic crystalline solid. The relative density is 7.510. Insoluble in water and organic solvents.
Tungsten disulfide can be used as a lubricant, with better performance than molybdenum disulfide, lower friction coefficient, higher compressive strength, and lubricity at 1316°C. Used as a high-temperature solid lubricant, used alone for high-temperature, high-pressure, high-speed, high-load, and transport equipment in chemically active media.
Tungsten disulfide nanoparticles are mainly used as petroleum catalysts, dry film lubricants, additives for high-performance lubricating grease, batteries, semiconductor materials, etc. They can also be used as effective catalysts for new inorganic functional materials, paving the way for improving the trend of global warming.
