What is a tungsten crucible?

Tungsten crucible is one of the tungsten metal products produced through powder metallurgy technology. Stamping forming, or using pure tungsten plates, tungsten sheets, and pure tungsten rods processed by corresponding processes. The working environment can reach up to 2400 ℃, tungsten has a high melting and boiling point, good high-temperature strength, wear and corrosion resistance, high thermal conductivity, low coefficient of thermal expansion, and good hardenability. Tungsten crucibles are widely used in industries such as rare earth smelting, quartz glass, electronic spraying, and crystal growth.
 

The use of tungsten crucibles

Due to the high melting point of tungsten reaching 3410 ℃, tungsten crucibles are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces, rare earth smelting furnaces, etc. Their working temperature environment is generally above 2000 ℃. Especially for sapphire single crystal growth furnaces, tungsten crucibles with characteristics such as high purity, high density, no internal cracks, precise size, and smooth inner and outer walls play a crucial role in the success rate of crystal seeding, quality control of crystal pulling, detachment and sticking of the pot, and service life during sapphire crystal growth.
