The Manufacture and Applications of Tungsten Crucible
What is Tungsten Crucible?
Tungsten crucible is one of the hot products of tungsten. In terms of process, tungsten crucible is often made through sinter molding, impact molding, spinning molding, and welding fabrication. Sinter molded tungsten crucible is typically applied in sinter powder metallurgy. A small-sized tungsten crucible is usually manufactured by turning process using a tungsten rod. Tungsten crucibles can be made by processing a pure tungsten plate, tungsten sheet, and tungsten rod.
What Are the Applications of Tungsten Crucible?
Thanks to tungsten’s high melting point, high-temperature strength, great pyro conductivity, and good hardenability, tungsten crucible can be used under vacuum and inert gases below 2600℃. Tungsten crucible is widely used in industries including rare earth metallurgy, quartz glass, MOCVD equipment, and electronic spraying. In addition, tungsten crucibles can be used for sapphire crystal growth furnaces due to their high-temperature resistance, low pollution, and other excellent characteristics. Also, because the tungsten crucible is with high purity, high density, accurate dimensions, and no inner cracks, it can greatly increase the success of sapphire crystal growth.
