Molybdenum disulfide is a chemical compound made up of molybdenum and sulfur. It is often used as a lubricant because it can reduce friction between surfaces. This makes it valuable in various industries, including automotive and aerospace, where smooth operation is crucial. Its unique layered structure allows it to slide easily, similar to how graphite works. In addition to its lubricating properties, molybdenum disulfide is also used in electronics and as a catalyst in chemical reactions. Researchers are exploring its potential in advanced materials, such as in batteries and solar cells, due to its excellent electrical and thermal conductivity.
