4.Application of Sintered 99.95% Tungsten Crucible For Sapphire Crystal Furnace:
Since the melting point of tungsten has reached 3410℃, tungsten crucible is widely applied in industry furnace such as sapphire growth furnace, quartz glass melting furnace, and a furnace for smelting rare earths. The tungsten crucible's operating environment has a temperature of more than 2000°C. For sapphire crystal growth furnace, high-purity, high- density, a tungsten crucible without an internal fracture that also has precise measurement and a smooth surface has a significant impact on the sapphire growing process's success ratio for seed growth, pulling crystal quality control, metamictization pot commitment, and service life.
Tungsten crucible Liners are highly helpful in electron-beam evaporation because they frequently speed up the rate at which the material is being deposited and make switching between different evaporation materials easier. There are many sizes of Crucible Liners.
