Product parameters

Product application

Since the melting point of tungsten is as high as 3410°C, tungsten crucibles are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass smelting furnaces, and rare earth smelting furnaces.

The working temperature environment they use is generally above 2000°C. Especially for sapphire single crystal growth furnaces, tungsten crucibles with characteristics such as high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, etc. are very important for the success rate of seed crystals, quality control of crystal pulling, etc. during the growth process of sapphire crystals.

Decrystallization and sticking to the pot and service life play a key role.
