is a strip-shaped material made of molybdenum, which is usually used in industrial applications in extreme environments such as high temperature, high pressure, and high strength, such as in automotive, aerospace, petroleum, and chemical industries.
Molybdenum has excellent high-temperature oxidation resistance, corrosion resistance, and high-strength properties, and is rarely contaminated by radioactivity, so it is also widely used in the nuclear industry. In addition, molybdenum metal is also used to make filaments, electronic components, alloys, etc.
1. Feature
- High purity, usually 99.95% or higher;
- High density, 10.2 g/cm³;
1) Chemical properties
2) Physical properties
- High melting point, 2610 degree ;
2. Production Process
1) Molybdenum powder preparation: use the electrochemical reduction method, hydrogen reduction method, and other methods to convert molybdenum concentrate into molybdenum powder.
2) Powder metallurgy method: the powder metallurgy method is used to extrude the molybdenum powder and then sinter it.
3) Mosaic method: Fill molybdenum powder into a metal tube, heat, and sinter, and then obtain molybdenum rods through stretching, finishing, and other processes.
3. Working Principle
Molybdenum rods are widely used in high temperature environments because of their high-temperature oxidation resistance and mechanical strength. It is mainly used as a material for heating elements, vacuum tube electrodes, molds, etc. At the same time, it also has important applications in the nuclear industry. Due to the low thermal expansion coefficient and good thermal conductivity of molybdenum rods, it can be used to make thermocouples, temperature detectors and heaters, and other equipment, which can withstand high temperature and high-pressure environments.
4. Application Field
1) Electronics and semiconductor industry: used in the production of mid-to-high-end electronic products such as chips and flat panel displays.
2) Vacuum melting and heat treatment: It can be used in the vacuum melting and heat treatment industry to manufacture fixed heaters and boats, etc.
3) Optical industry: used in the manufacture of converging mirrors, MPF windows (mid-plane-focusing window), IR Barkhausen windows (IR Barkhausen window), etc.
4) Medical industry: R&D and manufacturing for the manufacture of radiotherapy devices.
