Product Description
Product Description:
Tungsten crucibles are one of metal tungsten products, which are mainly divided into sintering molding (applied to powder metallurgy technology), stamping molding, and spinning type. It is formed by turning tungsten rods (generally the size is relatively small), and there are many kinds of welding shapes. It is made of pure tungsten plates, tungsten sheets and pure tungsten rods through corresponding processes. Tungsten crucibles can be used in vacuum inert gas below 2600 ℃. 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 crucibles are widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.

Applications:
Because the melting point of tungsten is as high as 3410°C, tungsten crucibles are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces, and rare earth smelting furnaces. The working temperature environment is generally above 2000°C. Especially for sapphire single crystal growth furnaces, tungsten crucibles with high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, etc. have a great influence on the seed crystal success rate, crystal pulling quality control, Decrystallization sticky pan and service life play a key role.
Packing and Shipping:
Packaging and Shipping for Tungsten Crucible
Tungsten crucibles are usually packaged in wooden boxes, which are filled with foam or other cushioning materials. In order to ensure the safety of the crucible during the shipping process, these wooden boxes must be tightly sealed and secured with straps or bubble wrap.
