Description:

   Tungsten crucible is one of the tungsten metal products. It is mainly divided into sintering molding, stamping molding and spinning type. It is formed by turning tungsten rods and welded into various shapes. It is made of pure tungsten plates, tungsten sheets and pure tungsten rods processed by corresponding processes.

Specifications:

Application:

Tungsten crucible can be used in vacuum inert gas below 2600 degrees. Tungsten has a 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.

Metal Alloy High Purity Tungsten Crucibles are widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries·

Since the melting point of tungsten is as high as 3410°C, pure Tungsten melting crucible are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass smelting furnaces, and rare earth smelting furnaces. The working temperature environment they use is generally above 2000°C.

Especially for sapphire single crystal growth furnaces, W crucibles with characteristics such as high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, etc. are very important for the success rate of seed crystals, quality control of crystal pulling, etc. during the growth process of sapphire crystals. Decrystallization and sticking to the pot and service life play a key role.
