Aluminum Nitride Crucible

Email us

Aluminum nitride (AlN) ceramics have good corrosion resistance and stability at room temperature and high temperatures. They only decompose at 2450°C and can be used as high-temperature refractory crucibles. Aluminum nitride crucible cannot be wetted by copper, aluminum, silver, and other substances and resists the dissolution of aluminum, iron, and aluminum alloys, so it can be a good container. Since aluminum nitride is stable against molten salts such as gallium arsenide, using aluminum nitride crucibles instead of glass to synthesize gallium arsenide semiconductors can eliminate contamination from silicon in the glass and obtain high-purity gallium arsenide semiconductors. We can produce aluminum nitride ceramic crucibles with very smooth inner surfaces, which can extend service life.

Edgetech Industries, Advanced Ceramics Division supplies high-quality Aluminum nitride (AlN) Ceramics Crucible at competitive prices.
