Molybdenum disulfide The main component of 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, dilute sulfuric acid or other organic solvents. It's also generally insoluble with alkalis, acids, and other organic compounds. But it dissolves in 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 molybdenum diulfide lubricating product, but you can also add copper corrosion inhibitors.

Where is molybdenum 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 linear semiconductor. Molybdenum Disulfide may also be used to dehydrogenate 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 metallic sheen, slick to the touch and insoluble. 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 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.

Additionally, molybdenum diulfide powder is a potential new material to be used in the manufacture of transistors. In comparison with graphene (also a 2-dimensional material), molybdenum diulfide is has a gap in the energy band of 1.8eV. Graphene lacks an energy gap. The application of molybdenum diulfide in nano-transistors is therefore very broad.

Molybdenum disulfide (MoS2) This solid lubricant is often referred to as "the King of Solid Lubricants."
Molybdenum diulfide, or molybdenum powder, is made from a natural concentrate of molybdenum after a chemical purification. The product's color is black, with a metallic sheen, a slight grayish tinge, and it is insoluble in any liquid. Molybdenum diulfide offers the benefits of being non-sticking and dispersible. It can also be added to greases in order to produce a non-sticky, colloidal state. This will increase the lubricity as well as the extreme pressure.

It is suitable for equipment that is subjected to high temperatures, pressures, speeds, and loads. Molybdenum Disulfide has the ability to increase friction and reduce friction when used at low temperatures, while reducing friction and friction when used at high temperatures.

Molybdenum diulfide is used in a variety of ways as a solid lubricant.
1. Lubrication in wide temperature ranges: the lubricating oil or grease can be applied from about 60degC to around 350degC. The solid molybdenum disulfide lubricant has a temperature range from 270degC up to 1000degC.

2. Lubrication for heavy loads: The oil films of general lubricating ointments and greases are only capable of bearing relatively small load values. Once the load is exceeded, the oil film will rupture. The solid lubricating layer can support a load of 108Pa on average.

3. Lubrication for vacuum conditions. Under high vacuum, lubricating greases and oils are highly evaporative. They can easily damage vacuum environments and impact the performance of other parts. Lubrication is usually done with solid molybdenum-disulfide lubricants.
4. Lubricants under radiation conditions: Liquid lubricants that are used in general will decompose or polymerize and lose their lubricating characteristics. Solid lubricants offer better radiation resistance.

5. Lubrication of conductive surface: The friction between conductive surfaces like motor brushes, conductive slides, solar collector rings or sliding electrical contacts of artificial satellites that work in a vacuum can be made out of metal or carbon graphite.

6. Molybdenum disulfide is suitable for harsh environmental conditions. For example, transportation machinery, engineering equipment, metallurgical or steel industry institutions, mine machinery and other transmission components that are exposed to dust, sand and high temperature, as well as humidity and heat, Molybdenum diulfide can be used as a lubricant.

7. Corrosive Environments: Ship machinery, chemical machinery, and other transmission parts operating in corrosive mediums such as seawater, water (steam), acid, alkali or salt must be able to withstand different levels of chemical corrosion. Molybdenum Disulfide Solid can be used to lubricate the transmission parts that are working in such a situation.

8. The environment must be very clean. Transmission components in electronic, textile, food and medicine machines, as well as paper and printing equipment, need to remain contaminant-free. Solid lubricants such MoS2 can help with this.

9. Some transmission components do not require maintenance. Others need less frequent maintenance. MoS2 solid greases are convenient and economical in these cases.
