Stanford Advanced Materials (SAM) manufactures various tungsten crucibles and other Tungsten parts such as tungsten heaters, heat insulation screens, tungsten sheets, supports, etc. We provide tailor-made products according to your drawings and specific requirements.
Tungsten is a highly durable metal that exhibits remarkable resistance to molten metals and metal oxides. It boasts high-temperature resistance and low pollution, making it a preferred material for various industrial applications.
The tungsten crucible produced by CVD has some characteristics such as a high density of up to 98.5% of theoretical density, high purity of 99.9999%, particular microstructure of columnar crystal or multilayer columnar crystal, etc.

Chemical Vapor Deposition (CVD) Tungsten Crucible
Tungsten crucibles are particularly useful in the technology of growing monocrystals from molten corundum, as well as in electronics and thermal vaporization. These crucibles play a crucial role in high-temperature furnaces due to their impressive melting point. In addition, tungsten crucibles and other parts are ideal for sapphire crystal growth and rare-earth melting, thanks to their exceptional high-temperature resistance and low pollution properties.
