Abstract

A novel method is proposed to prepare Al₂O₃/AlN composite powders. The composite powders were synthesized by direct nitridation of Al₂O₃ powders in Ar/N₂ plasma. The processing characteristics were studied. The results show that the particle size of the initial materials the nitrogen plasma gas flow rate and the power of the plasma generator are important factors that influence the phase composition of the Al₂O₃/AlN composite powders. Post treatment of the Al₂O₃/AlN composites in nitrogen atmosphere was carried out. Microstructure analysis showed that the composite powders are spheroids, with the small particle size AlN formed on the surface of the Al₂O₃.
