The Uses of Molybdenum


Molybdenum is of wide uses. Adding molybdenum into steel and iron can enhance intensity, tenacity, and corrosion resistance, making it one of the best alloy addition elements. The amount of Mo used as an alloy addition element accounted for 85% of its total usage. Nickel-based alloy adds more Mo than other alloys: 15%~30% can greatly improve the corrosion resisting property; nickel-based alloy of 18% Mo and 18% chrome can withstand high temperature of 1093℃; 50% molybdenum and 50% rhenium molybdenum rhenium alloy seamless tube has great high temperature property, and can be used even when it is close to its melting point. Molybdenum is widely used in electronic industry (such as silicon wafer bearing). It can also be used in the aviation and aerospace industry as high temperature resistance components. Compounds of Mo can be used as catalyst and reagent. It can also configure the pigment. Molybdenum disulfide solid lubricant is renowned as “the king of lubrication”. Molybdenum is also one of the terrific microelement chemical fertilizers in agriculture.

Mo is mainly used in steel industry to improve the steel’s intensity, rigidity, and corrosion stability. Molybdenum can be used to make large electrode and grid, amplifier, and transmitting tube; its alloy is of heat and corrosion resistance, and can be used as the heat-resistant components in astronavigation, rocket, and nuclear industries; molybdenum trioxide is used as catalyst in chemical industry and oil industry; molybdate can be used as pigment and dye, and when added into enamel, it can make the combination of enamel and steel firm; molybdenum dioxide is available as solid lubricant.

Human production activities caused the artificial changes of Mo in nature. There are four sources of entering into human activities: molybdate fertilizer, urban sewage sludge, coal burning, the mining and processing of molybdenum minerals, and so on. Molybdenum in food is closely related to the place of origin’s soil and water conditions, and molybdenum content of the same food can differ greatly. China is such a vast country, with complex climate, topography, water and soil conditions, food processing and eating habits are also diverse. There are many factors that can affect molybdenum and other micro-nutrients in foods. The microelement composition standards and major food sources of regional food are to be developed for guiding people to choose food, and deploy a balanced diet, which will be very beneficial to health and animal husbandry development.
