Sintering of Aluminum-Oxynitride Powder Prepared by Self-Propagating High-Temperature Synthesis

Resumo

Sintering of aluminum-oxynitride powders prepared by self-propagating high-temperature synthesis in a nitrogen-containing gel was researched. Use of the powders without extensive mechanical grinding was problematical because of their low specific surface areas. Equipment fitted with grinding containers lined with high-density plates and grinding balls made of the same material, 9Al₂O₃·5AlN, were required to solve this problem.
