Application of molybdenum
It has been more than 100 years since molybdenum, which was discovered by scientists, was actually used in production. Because it is like titanium, tungsten and other strategic metals, industrial production requires its purity is very high, and purification is very difficult. In 1893, mosson, a scientist, produced 96 percent pure molybdenum through a high temperature reaction between carbon and molybdenum trioxide.
Solid molybdenum was first used in the military. Due to its high strength, low thermal expansion coefficient and strong thermal conductivity, solid molybdenum has been added to alloy steel, stainless steel and other alloys for the manufacture of various military equipment. Pure molybdenum wire made of solid molybdenum is used for high temperature electric furnace and cutting materials.
During the first world war, the amount of tungsten increased greatly, which was far from enough for the war. Scientists discovered that molybdenum was half as light and stronger than tungsten, so it was used instead to make battleships and gun insides. For the first time, molybdenum is in full swing.
Interestingly, after the end of world war I, demand for molybdenum collapsed as the war diminished. Scientists began to explore new USES for molybdenum and its compounds. They found that molybdenum disulfide, with its layered structure, slides easily from layer to layer, making it a solid lubricant. These are more effective than the lubricating grease of molybdenum disulphide lubricant, widely used in the mechanical industry and aerospace.
