Product Description:
Tungsten crucible (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. The use of tungsten rod turning molding (general size is relatively small), welding molding a variety of pure tungsten plate, tungsten and pure tungsten rod by the corresponding process. The tungsten crucible can be used in a vacuum inert gas at 2600 degrees or less. Tungsten has high melting point and boiling point, good high temperature strength, wear resistance and corrosion resistance, high thermal conductivity, small thermal expansion coefficient, and good hardenability. Tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.
Material characteristics:
The characteristics of tungsten crucible include high specific gravity, high melting point, high boiling point, low vapor pressure, small evaporation rate, low thermal expansion coefficient, corrosion resistance, wear resistance, good thermal conductivity, etc. Note: According to different manufacturing processes, tungsten crucibles can be divided into forging forming, sintering forming, welding forming, stamping forming, spinning forming, etc. The densities of forging forming and sintering forming are greater than 19.35g/cm3 and 18.5g/cm3 respectively. Adding a certain amount of rare earth elements in the manufacture of pure tungsten crucible can improve the oxidation resistance of the crucible and prolong the service life of the product.
Product use:
Tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries, mainly used as rare earth metal smelting furnace, quartz glass melting furnace, induction furnace heating body, single crystal furnace high temperature container, sapphire single crystal growth furnace, high temperature vacuum furnace and other industrial furnaces, its working temperature is generally above 2000°C. Note: In the process of sapphire crystal growth, the tungsten crucible should have the characteristics of no internal crack, accurate size, smooth inner and outer walls, etc.
