- industrial applications
Aluminum nitride ceramics can be used as containers for vacuum evaporation and metal smelting, especially suitable for vacuum evaporation crucibles for aluminum, because aluminum nitride ceramics are heated in a vacuum with low vapor pressure and will not pollute aluminum even if they are decomposed. In the semiconductor industry, using aluminum nitride crucibles instead of quartz crucibles to synthesize arsenide can completely eliminate the pollution of Si on GaAs and obtain high-purity products.

Product detail
Aluminum nitride ceramics (AlN ceramic) have excellent thermal conductivity (5-10 times that of alumina ceramics), low dielectric constant and dielectric loss, reliable insulation performance, excellent mechanical properties, non-toxic, high temperature resistance, and chemical corrosion resistance , and the coefficient of thermal expansion is similar to that of silicon, which is widely used in communication devices, high-brightness LEDs, power electronic devices and other industries.
