The application of molybdenum
Molybdenum is mainly used in iron and steel industry, most of which is directly used in steelmaking or cast iron after industrial molybdenum oxide is pressed, and a small part is melted into ferro molybdenum and then used in steelmaking. The molybdenum content in low alloy steel is less than 1%, but this aspect accounts for about 50% of total molybdenum consumption. The corrosion resistance of stainless steel can be improved by adding molybdenum. The strength and wear resistance of iron can be improved by adding molybdenum into cast iron. Nickel-based superalloy containing 18% mo has the characteristics of high melting point, low density and low thermal expansion coefficient, and is used in the manufacture of various high temperature components in aviation and aerospace. Molybdenum metal is widely used in electronic devices such as electron tubes, transistors and rectifiers. Molybdenum oxide and molybdate are excellent catalysts in chemical and petroleum industries. Molybdenum disulfide is an important lubricant used in the aerospace and mechanical industries. Molybdenum is one of the essential trace elements in plants and is used as trace element fertilizer in agriculture.
Pure molybdenum wire for high temperature electric furnace and edM and wire cutting processing; Molybdenum sheets are used to make radio equipment and X-ray equipment; Molybdenum is resistant to high temperature ablation, mainly used in the manufacture of gun bore, rocket nozzle and tungsten wire bracket of electric bulb. Molybdenum is one of the seven micronutrients required for plant growth and development, without which plants cannot survive. Animals need molybdenum as much as fish do plants.
