Tungsten Crucible
Since the melting point of tungsten has reached 3410ºC, Tungsten crucible is widely applied in industry furnace such as sapphire growth furnace. Quartz glass melting furnace and rare earth smelting furnace. The temperature in working environment of tungsten cruible is above 2000ºC, for sapphire crystal growth furnace, high-purity. High-density, no internet crack tungsten crucible with other features of exact measurement and smooth inner surface has decisive influence on success ratio of seed growth quality control of pulling crystal metamictization pot-committed and service life during sapphire growth process.
