Because tungsten has a melting point of 3410°C, high purity, high density, no internal cracks, precise dimensions, and smooth inner and outer walls, it is widely used in sapphire single crystal growth furnaces, quartz glass melting furnaces, rare earth smelting furnaces and other industrial furnaces The working temperature environment of the core container inside is generally above 2200℃. The tungsten crucible plays a key role in the success rate of seeding, the quality control of crystal pulling, the potting and the service life of sapphire crystal growth.
Application: Mainly used in metallurgical industry, mechanical processing, glass and ceramic industry and other fields
