Molybdenum(IV) Sulfide (MoS₂)

Molybdenum(IV) sulfide (MoS₂), or Molybdenum Disulfide, is a dark gray or black powder that is a solid-state lubricant. It is a two-dimensional layered material, giving it a low coefficient of friction and high chemical, thermal, and pressure stability.
Typical Chemical Analysis

MoS₂= 98.0% min.
Acid (insoluble)= 0.50% max.
Fe= 0.25% max.
MoO₃= 0.05% max.
H₂O= 0.02% max.
Oil= 0.05% max.
C= 1.50% max

Molybdenum Disulfide Powder Grades

Superfine: 1.5 microns avg.*

Technical fine: 6 microns avg.*

Technical: 30 microns avg.*

* As determined by Leeds & Northrup Microtrac particle size analysis

Typical Applications

Molybdenum(IV) sulfide is widely used as a solid lubricant, including in aircraft engines. Polymers consisting of molybdenum(IV) sulfide, such as nylon, Teflon, and vespel, possess improved strength and reduced friction. Other applications are as an intermediate or co-catalyst for desulfurization in petrochemistry or as a catalyst in water electrolysis. It is useful as a filament material in many electrical applications. It is also used as a component of photoelectrochemical and microelectronics applications.

Packaging Options

One lb. can, 5 lb. can, 25 lb. pails, 200 lb. fiber drum, super sacks, and loose bulk

Classification

Molybdenum(IV) sulfide TSCA (SARA Title III) Status: Listed
