It has been more than 100 years since the element
molybdenum, discovered by scientists, was actually used in production. Because it and
titanium,
tungsten and other strategic metals, industrial production of its purity requirements, and purification is very difficult. In 1893, scientist Mossen reacted carbon and molybdenum trioxide at a high temperature, and finally produced a solid molybdenum with a purity of 96%.
Solid molybdenum was first used in the military. Due to its high strength, low thermal expansion coefficient and strong thermal conductivity, solid molybdenum is added to alloy steel, stainless steel and other alloys for manufacturing various military equipment. Pure
molybdenum wires made from solid molybdenum are used in high temperature furnaces and cutting materials.
During the first world war, the use of tungsten increased dramatically, far more than the war. The scientists found that molybdenum was half as light and stronger than tungsten, so they used it instead to make warships and gun bore. For the first time, molybdenum is in full swing.
Interestingly, after world war I, demand for molybdenum dropped sharply as the war abated. Scientists began to explore new USES for molybdenum and its compounds. They found that molybdenum disulfide has a molecular layered structure that slides easily from layer to layer, so it ACTS as a solid lubricant. Molybdenum disulfide lubricants, which are more effective than lubricating oils, are widely used in the mechanical industry and aerospace fields.
