Molybdenum disulfide The main component in molybdenite is powder, which has the chemical formula MoS2. It is a dark solid powder that has a metallic sheen.

What property does molybdenum disulfide have?

The powder of molybdenum is not soluble when mixed with water, concentrated sulfuric or dilute acids. It’s also insoluble for most alkalis, organic solvents and other acids.
It is important to note that molybdenum powder contains active sulfur. This can cause copper to be corroded. In many books and articles on lubricant add-ons, it is mentioned. When parts made of copper alloys and copper need to be greased, it’s not impossible to use lubricants containing molybdenum sulfide, but you can also add copper corrosion inhibitors.

Where is the molybdenum sulfide powder used?

Molybdenum diulfide is a solid lubricant that can be used at high temperatures or pressures. It is diamagnetic and can be used to convert energy and as a semiconductor that shows P-type and N-type conductivity. Molybdenum Disulfide may also be used to dehydrate complex hydrocarbons.

Molybdenum Disulfide Powder is also called the “king of advanced liquid lubricants.” Molybdenum powder is solid molybdenum that has been purified chemically and changed in molecular structure. This product is black, with a slight metallic luster. It’s slippery and not soluble in water. The product’s advantages are its good dispersibility, and that it is non-sticking. It can be mixed with various greases to produce a non-sticky, colloidal state. This can increase the lubricity of the grease and its extreme pressure. It can be used for mechanical conditions that require high temperatures, high pressures, high speeds, and high loads.

Its main purpose in friction materials is reducing friction at low temperature, increasing friction at higher temperatures and having a small loss during ignition. It is volatile in friction materials.

The powder of molybdenum diulfide is also a good material to use for transistors. In comparison with graphene (also a 2-dimensional material), molybdenum diulfide is a more efficient two-dimensional material. It has an energy gap of 1.8eV while graphene lacks an energy gap. The application of molybdenum diulfide in nano-transistors is therefore very broad.
