Molybdenum disulfide is the king of high-grade solid lubricants

What is molybdenum disulfide?

Molybdenum disulfide powder is a solid lubricant. Because of its low friction coefficient, the friction resistance between friction devices is small to save power consumption. Molybdenum disulfide is resistant to moisture, water, alkali, and acid. Molybdenum disulfide plastic or powder can be used to melt molding parts, saving a lot of non-ferrous metal. Molybdenum disulfide is a high-temperature lubricant used in harsh working conditions for high-temperature, high-friction parts. Black solid powder with a metallic luster. Chemical formula MoS2, melting point 1185, density 4.80 g/cm 3 (14), Mohs hardness 1.0 ~ 1.5. Decomposition begins at 1370 and is decomposed into metals molybdenum and sulfur at 1600. When 315 is heated in the air, it begins to be oxidized. As the temperature rises, the oxidation reaction is accelerated. Molybdenum disulfide is insoluble in water, only soluble in aqua regia, and boiled concentrated sulfuric acid.

 

Preparation of molybdenum disulfide

The method of molybdenum disulfide is (1) the direct combination of molybdenum and sulfur. Molybdenum trioxide and hydrogen sulfide gas action. The mixture of molybdenum trioxide, sulfur, and potassium carbonate is fused. Molybdenum disulfide is an important solid lubricant suitable for high temperatures and pressure. It is also diamagnetism and can be used as a linear photoconductor and a semiconductor showing P-type or N-type conductivity. It has the function of rectification and energy exchange. Molybdenum disulfide can also be used as a catalyst for dehydrogenating complex hydrocarbons.

 

Molybdenum disulfide is king of high-grade solid lubricants

It is also known as the "king of advanced solid lubricants." After chemical purification and molecular structure change, Molybdenum disulfide is a solid powder made from natural molybdenum concentrate powder. This product's color is black, slightly silver gray, with a metallic luster, touch a sense of smoothness, and insoluble in water. The product has the advantages of good dispersion and non-binding. It can be added to various oils to form a colloid state that does not bond, increasing grease lubricity and extreme pressure. Also suitable for high temperature, high pressure, high speed, and high load mechanical working state, prolonging the life of the equipment. The main function of molybdenum disulfide used in friction materials is to reduce friction at low temperatures, increase friction at high temperatures, small burning loss, and volatile in friction materials; Reduce friction.

 

Price of molybdenum disulfide

Molybdenum disulfide particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Molybdenum disulfide. A large amount of large amount will be lower. The Price of molybdenum disulfide is on our company's official website.
