The main application areas of tungsten crucible include rare earth smelting, quartz glass melting, sapphire single crystal growth, semiconductor manufacturing, etc.
Rare earth smelting
Tungsten crucible plays an important role in rare earth smelting. Due to its high melting point, high strength and corrosion resistance, tungsten crucible can withstand harsh environments such as high temperature and corrosion to ensure the smooth progress of the smelting process. Sintered tungsten crucibles are widely used in rare earth smelting due to their high density, high purity and long life.
Quartz glass melting
Tungsten crucibles are also widely used in quartz glass melting furnaces as one of the important equipment for melting quartz glass. Its high temperature strength and corrosion resistance enable tungsten crucibles to stably melt quartz glass and improve the yield of quartz glass.
Sapphire single crystal growth
Tungsten crucibles also play a key role in the growth of sapphire single crystals. Due to its high purity, high density and no internal cracks, tungsten crucibles can greatly improve the success rate and quality of sapphire crystal growth, while extending its service life.
Semiconductor manufacturing
In the semiconductor manufacturing industry, tungsten crucibles are key components in the growth process of semiconductor materials such as single crystal silicon. Its high temperature resistance and corrosion resistance enable tungsten crucibles to operate stably in processes such as chemical vapor deposition (CVD) or physical vapor transport (PVT), improving the performance of semiconductor devices.
