General Information

Tungsten Crucibles (English name: Tungsten Crucibles) is one of the metal tungsten products, mainly divided into sintering molding (applied to powder metallurgy technology), stamping molding, spinning type. It is formed by turning the tungsten rod (the general size is relatively small), and the welding is various. The pure tungsten plate, the tungsten piece and the pure tungsten rod are processed by corresponding processes. Tungsten rhenium can be used in vacuum inert gases below 2600 degrees. Tungsten has a high melting point, high temperature strength, anti-wear and corrosion resistance, high thermal conductivity, small thermal expansion coefficient and good hardenability. Tungsten-rhenium is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.

Chemical Composition

Application

Since the melting point of tungsten is as high as 3410 ° C, tungsten rhenium is widely used in the core container of industrial furnaces such as sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace, etc., and its working temperature environment is generally above 2000 °C. Especially for the sapphire single crystal growth furnace, the high-purity, high-density, no internal crack, accurate size, smooth inner and outer walls, etc., the growth rate of the seed crystal during the growth of the sapphire crystal, the quality control of the crystal pulling, The degumming pan and the service life play a key role.
