Molybdenum disulfide CAS 1317-33-5 MoS2

Molybdenum disulfide, the main component of molybdenum pyroxene, lead-gray to black solid powder, slippery on contact, odorless, belongs to the hexagonal or rhombohedral crystal system, similar to graphite, with a metallic luster; molybdenum disulfide is a good solid lubricant material, in high temperature, low temperature, high load, high speed, chemical corrosion and modern ultra-vacuum conditions, equipment have excellent lubricity; can be used as friction improver ( It can be used as friction modifier ( friction reducer), antiwear agent, extreme pressure agent and antioxidant; widely used in aviation industry (vacuum radiation lubrication), automobile industry (fixer and components), anti-seize industry (machinery industry) (general lubrication), mining industry, military industry, shipbuilding, heavy industry, bearing industry, gear industry and assembly industry, etc. It is also used as additives to various lubricants, manufacture of molybdenum compounds, catalytic hydration and desulfurization catalysts, It is also used as additives for various lubricants, molybdenum compounds, catalytic hydrogenation and desulfurization catalysts, gas storage materials, photovoltaic cell materials, etc.

1. Performance and 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 addition to serving as the primary natural source of molybdenum, purified molybdenum disulfide MoS2 is an excellent lubricant when in the form of a dry film, or as an additive to oil or grease. The compound also is used as a filler in nylons, and as an effective catalyst for hydrogenation-dehydrogenation reactions.
