Abstract

Synthesis of A1N by direct nitridation of A1 at - 80OoC by nitrogen gas at 1 MPa was attempted. Commercial purity A1 reacted with nitrogen leading complete reaction, whereas no reaction was observed with high purity Al.The AlN powder compacts sintered at 1800OC and 1.7 GPa pressure had a microhardness of 12.0 GPa.
