Abstract

Aluminum oxynitride (AlON) powder, a synthesis method thereof by direct nitridation under high pressure and use thereof, which belongs to the field of ceramic powder are presented. In the method, pure-phase AlON powder is synthesized by direct nitridation under high pressure with aluminum powder and alumina powder as starting materials. The powder has a spherical-like morphology, with a particle size ranging from 5 μm to 15 μm. The powder has good dispersibility and uniformity, and higher sintering activity. AlON transparent ceramic (1.2 mm thick) prepared from the AlON powder has a linear transmittance of more than 84%. The batch yield is on kilogram-scale; therefore, the method is suitable for large-scale production of the AlON powder.
