Molybdenum disulfide is a new style of solid lubricating materials (or solid lubricant), it has a good lubricity, temperature resistance (high temperature and very low temperatures resistance), compression wear resistance, chemical corrosion resistance, adhesiveness and so on. So it has excellent lubricating effect on the equipments under high-speed, high load, high temperature, low temperature, high precision and the chemical corrosion working conditions. Molybdenum disulfide is selected from the molybdenite and was made of a shiny dark gray powder by chemical and mechanical treatment. You will have a fat creamy feel with your fingers grinding. The chemical formula of molybdenum disulfide is MoS2. The proportion of molybdenum disulfide is 4.8. Molecular weight of molybdenum disulfide is 160.07. The hardness of molybdenum disulfide 1-1.5 (Mohs). ( Mohs hardness: mineral resists to the scoring of the outside world and the ability to be pressed into the ground named hardness which is divided into ten degrees. The ranking: 1. talc, 2. gypsum, 3. calcite, 4. fluorite 5. apatite, 6. orthoclase, 7. quartz, 8. topaz, 9. corundum, 10. diamond) Mohs hardness of molybdenum disulfide is between talc and gypsum.
