Molybdenum and molybdenum alloys
Molybdenum and molybdenum alloy rods (strips), wires, plates, strips, foils and shaped products are commonly used in metallurgy, mechanical manufacturing, electronics, lighting and some high-tech fields. e.g. light filament support, core shaft wire, reflector screen; anode, gate, auxiliary electrode, gasket for electronics industry; vacuum electroplating, vessels for sputtering, boat dishes, heaters; heating elements for high temperature furnaces, electrodes, heat insulation screens; surface treatment for surfacing welding, spray plating; thermocouples for temperature measurement and protective covers; uo2 refining for burning boats, etc. Molybdenum has been further expanded in recent 10 years, such as hot spray plating with molybdenum powder or molybdenum wire, which has greatly improved the service life of piston rings and gears on automobiles; in the glass and refractory fiber industry, molybdenum can replace the previous ones.
Molybdenum wire. Platinum crucibles and electrodes have achieved great effects. The presence of high temperature molybdenum makes the application range of molybdenum in halogen mercury lamp and vacuum furnace more and more. In the die casting industry, molybdenum and its alloys can be used as die casting die materials for colored and ferrous metals. Heat-resistant molybdenum-based ceramic pipe is suitable for continuous measurement of oxygen top blowing converter in steelmaking process, and hot extrusion die;Molybdenum alloy head is widely used in seamless steel pipe and stainless steel pipe, which significantly improves productivity and product quality and reduces cost. The alloy formed by molybdenum and tungsten has excellent corrosion resistance(zinc liquid and zinc vapor). The vertical shaft and temperature measuring sleeve are widely used in Mo30W alloy, which greatly reduces the shutdown maintenance and improves the working conditions. MoSi2 can be used as the heating element with the temperature of 1700℃ in the atmosphere, and it can be used as the crucible for rare earth smelting and some single crystal drawing instead of precious platinum crucible. . The application of molybdenum in chemical industry is becoming more and more attractive, especially the application of molybdenum compound in chemical industry is developing rapidly. Although molybdenum has been in a depressed state in recent years, the application of molybdenum compound is still in the long term and has developed towards polypolarization. Molybdenum and molybdenum alloys are highly stable in many reaction media, which are widely used in chemical industry, petroleum refining and glass light industries, such as chemical equipment lining, parts, valves, steam pipes, heat exchangers, reboilers, etc. Currently, molybdenum and molybdenum alloys have been used to produce, such as acids, bases, salts, molten glass, and some of the various equipment components that work in a gas medium. Such as large valves and heat exchangers in hot concentrated sulfuric acid system. Molybdenum and molybdenum alloys may also be used for equipment that are said to achieve chlorination at 320°C and higher pressures. The application of molybdenum compounds mainly includes the following aspects:catalyst and catalytic activator, lubricant and its lubricating additives, pigments, dye, paint and ink, water quality and medium cyclic etching agent, composite ion exchanger, battery, flame retardant, smoke retardant and breather, trace element additive, molybdenum compound fertilizer, superconducting material, ceramic material, polymer material filler, energy storage material, gasoline additive, glass material, etc. It has been predicted that the development of new applications of molybdenum in the next 10 years may be predominantly represented in fine chemicals, which is likely to result in a breakthrough increase in molybdenum consumption.
