What is molybdenum sulfide?
This is the main component in molybdenite. It is a solid black powder with metallic luster. Molybdenum dioxide has the chemical formula MoS2. The melting point at 2375°C is MoS2, and its density is 4.80g/cm3 (14.5°C). Its Mohs hardness can range from 1.0 to 1.5. It starts to dissolve at 1370°C and then decomposes into metal molybdenum at 1600°C.
Molybdenum disulfide can not be dissolved in water, dilute or concentrated sulfuric, and is usually insoluble in alkalis, organic solvents, and acids. However, it is soluble in aqua regia, boiled concentrated sulfuric, and in organic solvents.
What are molybdenum disulfide’s applications?
Molybdenum disulfide can be found in many carbon brush additives used in the automotive and machinery industries. You can add it to lubricating oils, greases, PTFEs, nylons, and stearic acids to increase lubrication.
Molybdenum dioxide can also be used for non-ferrous metals release agents and as a lubricant to forging dies. This will help extend the service life, improve working conditions, improve the running state, prevent damage from the surface, and prevent cold welding. Make sure that the threaded connection is in its best condition when connecting.
Molybdenum diulfide can be mixed with volatile solvents and sprayed onto metal surfaces. It can also be added to engineering plastics for lubricating elements. Molybdenum sulfide can also be used directly in electronics, spraying or electroplating as well as hardware and screws.
Molybdenum disulfide can be used as a solid lubricant. It is particularly well-suited to high temperature and high pressure. It is diamagnetic, so it can be used to produce a line photoconductor or a semiconductor of P-type and N-type conductivity. Additionally, it has the functions rectification as well as energy conversion. Molybdenum dioxide can be used to catalyze the dehydrogenation complex hydrocarbons.
Molybdenum disulfide, also known as “the king among advanced solid lubricants”, is another name for it. This solid powder is made from natural molybdenum powder after chemical purification. Molybdenum disulfide’s color is black with a slight silver-gray metallic luster. It has a greasy feel and is not soluble in water. It is non-adhesive, dispersible and has a low rate of adhesion. It can be added with other greases to form a colloidal condition that doesn’t adhere to them. This can increase the lubricity as well as the extreme pressure of grease.
Molybdenum disulfide works well in extreme conditions, such as high temperature, high pressure, and high loads. It also prolongs equipment’s lifespan.
The main function molybdenum dioxidide serves in friction materials is reduce friction at low temperatures, increase friction at high temperatures, and minimize ignition loss.
