In the electrical and electronic industry can produce cathode, gate, high voltage rectifier elements, incandescent filament support. Its wear-resistant, heat-resistant, corrosion resistant properties make commonly used in the metal processing industry, to do film extrusion, die-cast model of the membrane and the core. Molybdenum alloy with high strength and high temperature strength, under the protection of the coating can be made rocket engine nozzle, heat shield and other parts. Since molybdenum and molybdenum alloy small thermal neutron absorption cross section, the nuclear fuel stability and good corrosion resistance to liquid metal in the atomic energy industry as a sheath material and core structural material gas cooled reactors. Before the glass used as an electrode for industrial molybdenum generation platinum, but also for a glass melting heating elements and an agitator.
Compounds of molybdenum in molybdenum as a second-rate solid lubricant, its performance is better than the whole story, can be used normally in the temperature range of -45 ~ 400 ℃. If the soil contains trace amounts of molybdenum may stimulate plant growth. Can trace molybdenum fertilizer applied soybean yield of 10% to 15%, rice production by 20% to 25%. Thus the compounds are also used in the production of molybdenum fertilizer. Molybdenum is mainly used in the steel industry, most of which is used directly in the post-industrial briquetting molybdenum steel or cast iron, a small part of a molybdenum smelting iron and then used in steelmaking. Low alloy molybdenum content is not more than 1%, but in this area of consumption accounted for about 50% of the total consumption of molybdenum. Stainless steel, molybdenum is added, to improve the corrosion resistance of the steel. Adding molybdenum in cast iron, iron can improve the strength and wear resistance. Nickel-base superalloys containing molybdenum 18% with high melting point, low density and low coefficient of thermal expansion properties, used in the manufacture of various high-temperature aerospace components. Molybdenum is widely used in metal tubes, transistors and rectifiers and other electronic devices. Molybdenum and molybdate in the chemical and petroleum industries excellent catalyst. Molybdenum disulfide is an important lubricant for the aerospace and mechanical industries. Molybdenum is one of the essential trace elements in plants, trace element fertilizers used in agriculture.
Pure molybdenum wire for high temperature furnace and EDM wire cutting there; molybdenum is used to manufacture radio equipment and X-ray equipment; molybdenum high temperature ablation, mainly for Cannon Barrel, manufacture rocket nozzles, tungsten bulb holder . Plus molybdenum alloy steel can improve the elastic limit, corrosion resistance and maintaining permanent magnetism, molybdenum is seven micronutrients in a plant growth and development needs, without it, the plant can not survive. Animals and fish, and plants, also need to molybdenum. In order to ascertain the precious metal trace elements molybdenum human, animal and plant required.
