Tungsten Crucibles High Purity W High Temperature Resistant Metal for Semiconductor Alloy Nuclear and Vacuum Metallurgy Applications

Semiconductor single crystal growth: During the pulling process of silicon single crystals, tungsten crucibles can withstand temperatures above and remain in contact with the molten silicon for a long time without undergoing chemical reactions. For III-V group semiconductor materials such as gallium arsenide and gallium nitride, which have higher melting points and stricter purity requirements, the growth temperature often needs to reach or above, and tungsten crucibles can provide a stable and highly pure melt environment. High-temperature alloys and functional material melting: Cobalt-based and nickel-based high-temperature alloys need to undergo vacuum arc melting or induction melting in a vacuum or inert atmosphere with a temperature as high as . Tungsten crucibles can maintain...
