What is a Molybdenum disulfide (MoS₂)?

Molybdenum disulfide (MoS₂) is a dark gray, solid inorganic compound with a layered structure. It occurs naturally as the mineral molybdenite and is highly valued for its chemical stability, heat resistance, and excellent lubricating properties. MoS₂ is widely used as a solid lubricant, especially in environments with high temperatures or vacuum conditions, making it essential in aerospace, automotive, and machinery industries. Due to its low friction coefficient, it effectively reduces wear between metal components and extends equipment lifespan. Additionally, molybdenum disulfide possesses electrical conductivity and semiconductor characteristics, which have led to its increasing use in nanotechnology and electronics. It is commercially available in various forms such as powder, spray, and paste, and is applied in bearings, gears, pistons, and as a component in advanced electronic materials.
