Preparation of Aluminum Oxynitride Powder by Solid State Reaction Method

摘要

Single-phase aluminum oxynitride powders were obtained by varying the holding temperature (T) and the weight percentage of (X-Al_2O_3 in Al_2O_3 (X) with nano-sized Al_2O_3 and AlN powders as raw materials. Influences of T and X on the phase composition of obtained powders were studied. The results showed that the content of aluminum oxynitride increased with increasing T or X. When X was 50% and T was 1750°C, obtained powders had better properties than those of others.
