The Application of aluminum nitride crucibles

1.Semiconductor manufacturing：

Aluminum nitride crucibles are used in the synthesis of compound semiconductors such as gallium arsenide (GaAs) to eliminate Si impurities in quartz crucibles and improve product purity. They can also work as substrates for ceramic heaters, electrostatic chucks, and other components, perfectly matching the high-temperature, high-precision, and insulation standards of semiconductor equipments.

2.Metal smelting and vacuum evaporation:

Aluminum nitride crucibles can serve as linings and crucibles for smelting furnaces in the demanding high-temperature. Standing as vacuum evaporation crucibles for metals like aluminum and copper, aluminum nitride crucibles with their low vapor pressure and high thermal conductivity, ensuring the stability and uniformity of the evaporation process and avoiding metal contamination.

3.Optics and optoelectronics:

The pure, colorless and transparent of aluminum nitride ceramics endow them with optimal optical properties. Aluminum nitride crucibles are designed to fabricate optical windows and growth crucibles for laser crystals, thereby meeting the special requirements of optical devices.
