Abstract

A combustion synthesis method has been developed for synthesis of A1N powder. The A1N products thus obtained were ground to have an average particle size of 2μm for sintering. Yttrium oxide was added to the A1N powder as sintering aid. The sintering was carried out in a microwave field at 2.45 GHz with a single-mode cavity. The specimens were sintered at temperature ranging from 1800 to 1900°C with soaking times of 30 min to 3 hrs. The highest thermal conductivity of the as-sintered specimen achieved 195 W/mK. The as-sintered specimen was then placed in the microwave cavity again and was reheated at 1800°C under reducing atmosphere for a time ranging from 30 min to 3 h. The thermal conductivity of the specimen could achieve 235 W/mK.
