Use

Molybdenum disulfide (MoS2) is one of the most widely used lubricants in space systems.it is a common additive that improves the antiseize properties of wheel bearing grease.Molybdenum disulfide (MoS2) has been used for many years as a solid lubricant because of its interesting friction-reducing properties related to its crystalline structure. MoS2 is a lamellar compound made of a stacking of S-Mo-S layers . In each of them, the molybdenum atom is surrounded by six sulfur atoms located at the top of a trigonal prism. The distance between a molybdenum atom and a sulfur atom is equal to 0.241 nm, whereas the distance between two sulfur atoms from two adjacent layers is equal to 0.349 nm. This characteristic was often used to explain easy cleavage between the layers and therefore the lubricating properties of MoS2.
