Abstract：
 The present invention belongs to the technology field of electrically insulating material preparation, which is a novel process for synthesizing high-performance aluminum nitride powder by utilizing the self-spreading combustion for synthesis, wherein thinning agent and addition agent are charged into the raw material aluminum dust, and are ground by rotary mill, then they are charged into a combustion synthesis reaction apparatus, nitrogen is charged under coarse vacuum, ignition composition is ignited and ammonia gas is charged simultaneously, thus aluminum nitride powder is synthesized from the raw aluminum dust.
