Company dynamics
Due to molybdenum being a refractory metal with a melting point of 2625 degrees, it has strong tensile strength, creep resistance, and good heat resistance at high temperatures. It has a low coefficient of thermal expansion, high thermal conductivity and conductivity, and good corrosion resistance to liquid metals, potassium, calcium, bismuth, cesium, and other molten salts. Therefore, it is applied in various forms in various fields of the national economy, such as aerospace and nuclear energy, lighting appliances and electronic devices, vacuum furnaces and protective atmosphere electric furnaces, metal pressure processing, glass industry, etc.
The rapid development of high technology has also opened up a very broad prospect for the new application and development of molybdenum sheets. The application of ultra-high purity molybdenum in microelectronics technology, MoSi2 produced by co splashing high-purity and ultra-high purity molybdenum with silicon, is used as a better wiring material for integrated circuits in microelectronics and as an advanced gate material in metal compound semiconductors. Due to the needs and rapid development of microelectronics technology, high-purity and ultra-high purity molybdenum have developed rapidly. For example, Germany and Russia have produced molybdenum with a purity of 99.999% using chemical and physical methods, respectively; The application of molybdenum in nuclear fusion reactor technology; The application of molybdenum sheets in superconducting materials, such as the production of PMS wires with a cross-sectional area of 20% and a diameter of 0.4mm using PbMo6S8 powder, is due to the fact that PbMo6S8 has an upper critical field of up to 60T.
Therefore, not only has it aroused great interest in the materials industry, but extensive research is also being conducted; The application of molybdenum in reinforcement technology, such as using particle strengthening agents, carbides of i, Zr, Hf, rare earth oxides, etc., has made molybdenum alloys that are superior to pure molybdenum, such as MHC, ZHM, M25WH, etc. These new alloys have significantly improved and enhanced recrystallization clarity and thermal strength.
