Description:
Tungsten crucibles are metal tungsten products, which are mainly divided into sintering (applied to powder metallurgy), stamping and spinning. Using tungsten bar turning forming (general size is relatively small), welding forming a variety of, using pure tungsten plate, tungsten sheet and pure tungsten bar by the corresponding process. Tungsten crucible can be used in vacuum inert gas below 2600 degrees.
Physical property:
Tungsten has high melting point and boiling point, good high temperature strength, anti-friction and corrosion resistance, high heat conductivity, small thermal expansion coefficient and good hardenability.
Application:
Tungsten crucibles are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and so on, because the melting point of tungsten is as high as 3410 C. The working temperature of tungsten crucibles is generally above 2000 C. For sapphire single crystal growth furnaces, tungsten crucibles with high purity, high density, no internal cracks, size, smooth inner and outer walls, etc. play a key role in the success rate of sapphire crystal growth, quality control of crystallization, decrystallization and sticking pot and service life.
