What is the application of molybdenum?
Jun 21, 2018

In 1782, Elm in Sweden had the mixture of charcoal and molybdenum in linseed oil sealed and burned, and molybdenum is obtained.


Molybdenum is an integral part of various enzymes. The lack of molybdenum can lead to caries, kidney stones, keshan disease, bone disease, esophageal cancer and other diseases. Both human and animal body has a strong internal stabilization mechanism for molybdenum, and the consumption of molybdenum by mouth is not easy to cause poisoning.

 

Molybdenum is a rare metal which is similar to tungsten in properties. The specific strength of molybdenum bar is the highest in more than 1000 ℃, so it is a useful high temperature structural material. The high temperature conductivity of molybdenum is better than iron and nickel. The expansion coefficient of molybdenum is about 30% of copper and is almost the same as that of the special glass that works with electrons.


Molybdenum is an important additive in metallurgical industry. Molybdenum can improve the heat resistance, corrosion resistance, wear resistance, toughness and hardenability of the alloy, so it is a very useful element in the alloy,like molybdenum wire alloy. Molybdenum can be used as heating and heat reflection materials of high temperature furnace because of the high melting point of, good conduction and thermal conductivity. The working temperature of electric furnace with molybdenum can reach 1700℃.


Molybdenum can be used to make cathode, grid, high-voltage rectifier components, filament support in incandescent lamps in the electronics industry. Its wear-resistant, heat-resistant and corrosion-resistant properties are often used in the metal processing industry, which can be used as extruded film, die casting film and mold core. Under the protection of coating, molybdenum can make rocket engine nozzle, heat shield and other parts due to the high melting point of molybdenum, good conductivity and thermal conductivity. Molybdenum and molybdenum alloys can be used in the atomic energy industry as a material for gas cooling reactor and core structural materials since the thermal neutron absorption cross section of which is small, and the stability of nuclear fuel and the corrosion resistance of liquid metal are good.


Molybdenum disulfide can be used as a solid lubricant in molybdenum compounds. Its performance is better than that of graphite, which can be normal used in - 45 ~ 400 ℃. Small amounts of molybdenum in the soil can stimulate the growth of plant. The application of trace molybdenum fertilizer could increase soybean yield by 10%~15% and rice yield by 20%~25%. So molybdenum compounds are also used in compound fertilizers.
