Characteristic
Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS2.
Chemical formula：MoS2
Molar mass：160.07 g/mol
Appearance：black/lead-gray solid
Density：5.06 g/cm3
Melting point：2,375 °C (4,307 °F; 2,648 K)
Solubility in water：insoluble
Solubility：decomposed by aqua regia, hot sulfuric acid, nitric acid
insoluble in dilute acids
Band gap：1.23 eV (indirect, 3R or 2H bulk)
~1.8 eV (direct, monolayer)
Application
It is widely used as a dry lubricant because of its low friction and robustness. Bulk MoS2 is a diamagnetic, indirect bandgap semiconductor similar to silicon, with a bandgap of 1.23 eV.
