Tungsten Crucible

tungsten-crucible

Brief introduction:

Tungsten crucible is one of tungsten products. It is mainly divided into sintering (applied to powder metallurgy technology), stamping, spinning type of tungsten crucible. Using pure tungsten plate, tungsten sheet and tungsten rod through the corresponding technology to produce tungsten crucible. Tungsten crucible can be used in vacuum inert gas under 2600 degrees.

Applications of tungsten crucible:

Tungsten crucible is widely used in sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other core containers of industrial furnace. Its operating temperature environment is more than 2000 degrees.

Characteristics of tungsten crucible:

Tungsten crucible has high purity, high density, no crack, precise size, smooth inside wall and outside wall.

The possible internal injuries of tungsten crucible, such as porosity, slag and cracks are double strictly inspected to ensure the quality of tungsten crucible.

The crystal structure of tungsten crucible is compact.
