Molybdenum disulfide is a component of molybdenite. Molybdenum disulfide powder is Black solid powder with a metallic luster. Molybdenum disulfide chemical formula is MoS2, Molybdenum disulfide melting point is 1185°C, Molybdenum disulfide density is 4.80g/cm3 (14°C). Mohs hardness 1.0～1.5. It starts to decompose at 1370°C and decomposes into metallic molybdenum and sulfur at 1600°C. It starts to be oxidized when heated at 315°C in the air, and the temperature rises and the oxidation reaction accelerates. Moly disulfide is insoluble in water, dilute acid and concentrated sulfuric acid. It is generally insoluble in other acids, alkalis and organic solvents, but it is soluble in aqua regia and boiling concentrated sulfuric acid. Slowly oxidized at 400 ℃ to generate molybdenum trioxide
