Overview and wide application of molybdenum disulfide

Overview of Molybdenum Disulfide

Molybdenum disulfide (or molybdenum) is an inorganic compound composed of molybdenum and sulfur.

Molybdenum disulfide is the main component of molybdenite. It is a black solid powder with metallic luster. The chemical formula of molybdenum disulfide is MoS2, the melting point is 2375°C, the density is 4.80g/cm3 (14°C), and the Mohs hardness is 1.0-1.5. It begins to decompose at 1370°C and at 1600°C into metallic molybdenum and sulfur.

Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid, generally insoluble in other acids, alkalis and organic solvents, soluble in aqua regia and boiled concentrated sulfuric acid.

Application of Molybdenum Disulfide

Molybdenum disulfide is used as a dry lubricant in greases, dispersions, friction materials and bond coatings. Molybdenum-sulfur complexes can be used in suspension, but are more commonly dissolved in lubricating oils at concentrations of a few percent. MoS2 is used as an additive for greases, friction materials, plastics, rubber, nylon, PTFE, coatings, etc.

1) Widely used in automobile and machinery industry, it is a good solid lubricating material.

2) Lubricants for drill bits, cutting tools and some non-oily and hard alloy steels; lubricant additives and film removers for non-ferrous metals.

3) Preparation of greases and additives for solid lubricating films, nylon filters and catalysts.

4) Synthetic molybdenum disulfide is used as a catalyst for desulfurization in refineries.

Molybdenum disulfide mixed with some volatile solvents can be sprayed on metal surfaces or added engineering plastics to make lubricating components. Molybdenum disulfide can be directly used in electronics, spraying, electroplating, hardware, screws and other industries.

Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure. It is also diamagnetic and can be used as linear photoconductors and semiconductors that display P-type or N-type conductivity, as well as rectification and energy conversion. Molybdenum disulfide can also be used as a catalyst for complex hydrocarbon dehydrogenation.

Molybdenum disulfide is also known as "the king of advanced solid lubricants". It is a solid powder made of natural molybdenum concentrate powder through chemical purification and changing the molecular structure. Molybdenum disulfide is black in color, slightly silver-gray, with metallic luster, greasy touch, and insoluble in water. It has the advantages of good dispersibility and non-adhesion. It can be added to various greases to form a non-adherent colloidal state, which can increase the lubricity and extreme pressure of the grease.

Molybdenum disulfide is suitable for mechanical conditions of high temperature, high pressure, high speed and high load to prolong the life of equipment.
