For years, people have recognized that the molybdenum-containing compounds have integrated reduce friction, wear resistance, improve extreme pressure, anti-oxidation overall performance. The molybdenum-containing compounds can be used as an internal combustion engine oil, gear oil, grease and some industrial oil antioxidant, anti-friction additives. From the 1940s to now, the development of the molybdenum-containing additive is about experiencing the first stage of the product is solid molybdenum disulfide powder:

 

The first to enter inside for anti-friction grease extreme pressure agent products are molybdenum disulfide powder. Extreme pressure from anti-friction performance point of view, it reflects more satisfactory results. Until today, there are still companies molybdenum disulfide powder used as an additive in the application of grease. But there are several major issues have not been a good solution: First, there will be precipitation in the oil problem, even if it is the so-called "nano-scale" Molybdenum disulfide is also more or less precipitation; used in grease will appear in the dispersion inequality, it can not give full play to its functions. Second, the problem of pollution, molybdenum disulfide powder not only for the lubrication of machinery and equipment for processing of products and produce pollution, but the latest research shows that the solid powder of molybdenum disulfide grease in waste discharge process, more serious on the environment pollution. Third, after all, is due to molybdenum disulfide solid powder at high pressure conditions to reduce adverse noise. Fourth purity problems (due to cost considerations, the present powder of molybdenum disulfide containing most of the high graphite component), which greatly affect the performance of the lubricant and its persistence. For these reasons, the foreign oil blending plant basically stopped using molybdenum disulfide powder, while most domestic enterprises are no longer used, but in some there are some special grease applications.
