Application:

       Due to the melting point of tungsten up to 3410 ℃, tungsten crucible is widely used in the production of sapphire furnace, quartz glass melting furnace, rare earth smelting furnace and other industrial furnace vessel, the use of industrial temperatures generally above 2000 ℃. Especially for sapphire single crystal growth furnace, the high purity, high density, no internal cracks, the precise size, and other characteristics of the smooth inner wall tungsten crucible during crystal growth on a sapphire seed crystal success rate, pulling quality control, de-crystal stick pan and life has played a key role.
