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 with water, concentrated sulfuric or dilute acids. It’s also generally insoluble with other alkalis and organic solvents. But it is soluble when heated in concentrated sulfuric and aqua regia.
It is easy for copper to be corroded by molybdenum powder, due to its high active sulfur content. 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 powder used?
Molybdenum diulfide is a solid lubricant that can be used at high temperature or pressure. It is diamagnetic and can be used to convert energy and as a linear semiconductor. 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, has a metallic sheen, and is slippery. It’s also insoluble in liquid water. This product has excellent dispersibility, and 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 is suitable for mechanical conditions with 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.
Moreover, molybdenum diulfide powder is also a material that can be used for the manufacture of transistors. In comparison with graphene (also a 2-dimensional material), molybdenum diulfide is a more efficient two-dimensional material. It has 1.8 eV energy band gaps, while graphene lacks this. The application of molybdenum diulfide in nano-transistors is therefore very broad.
