Characteristic
Tungsten disulfide is an inorganic chemical compound composed of tungsten and sulfur with the chemical formula WS2. This compound is part of the group of materials called the transition metal dichalcogenides.
Chemical formula:WS2
Molar mass:247.98 g/mol
Appearance:blue-gray powder
Density:7.5 g/cm3, solid
Melting point:1,250 °C (2,280 °F; 1,520 K) decomposes
Solubility in water:slightly soluble
Band gap:~1.35 eV (optical, indirect, bulk)
~2.05 eV (optical, direct, monolayer)
Magnetic susceptibility (χ):+5850·10−6 cm3/mol
Crystal structure:Molybdenite
Application
WS2 is used, in conjunction with other materials, as catalyst for hydrotreating of crude oil.
Lamellar tungsten disulfide is used as a dry lubricant for fasteners, bearings, and molds under the brand name Dicronite.
