摘　　要：将氧化铝粉体置于高能球磨机中,充入氮气直接进行氮化反应制备氮化铝,用XRD、SEM等仪器对氮化铝进行了表征。研究结果表明,直接氮化法和高能球磨法两者结合起来制备氮化铝是可行的;氧化铝在研磨18h后开始转化成氮化铝;研磨21h,氮化反应已相当完全;高能球磨结合直接氮化合成氮化铝是一种节能的材料制备方法。This article is described a way of synthesising AIN by direct nitridation of aluminum oxide powders in high energy ball mill which is filled with nitrogen. The resulting powders under different experiment conditions were characterized by XRD and SEM. The study results shown that it is feasible to be produced using direct nitridation combined with high-energy ball milling methods. The A1203 start to convert into AlN after milling for 18h. The reaction is fairly complete after milling for 21h. This method is an energy-saving process.
