Molybdenum Disulfide Powder
We provide molybdenum disulfide powder with purity 98% to 99.9%, particle size is 0.4-4.0µm. Molybdenum disulfide powder is used for wear-resistant coatings and lubricants. We can also provide nano molybdenum disulfide with purity 99.9%, particle size is 200nm. Nano powder can be used as lubricants and for nano composites.
Basic information of Molybdenum Disulfide Powder (MoS2 powder)
-CAS #: 1317-33-5
-Molecular formula: MoS2
-Appearance: black/lead-gray solid
-Melting point (℃): 1185
-Solubility: decomposed by aqua regie, hot sulfuric acid, nitric acid, insoluble in dilute acid and water
-Hazardous characteristics: the powder in high temperature will burn and react violently with peroxide.
Chemical Properties of MoS2 Powder
Molybdenum disulfide is stable in air or oxygen at normal conditions, but reacts with oxygen upon heating forming molybdenum trioxide:
2 MoS2 + 9 O2 → 2 MoO3 + 4 SO3
Chlorine attacks molybdenum disulfide at elevated temperatures to form molybdenum pentachloride:
2 MoS2 + 7 Cl2 → 2 MoCl5 + 2 S2Cl2
Molybdenum disulfide reacts with alkyl lithium under controlled conditions to form intercalation compounds LixMoS2. With butyl lithium, the product is LiMoS2.
Applications of Molybdenum Disulfide Powder
MoS2 Powder is used as additives in lubricating grease, friction materials, plastic, rubber, nylon, PTFE, thermal spray coating and so on.
