氮化铝(AlN)陶瓷由于兼具高热导率等许多优良特性,为人们所重视。作为制备AlN制品必由之路,AlN粉末的制备,主要采用两种方法,即铝直接氮化法(Geuther法)和Al_2O_3碳热还原氮化法(Serpek法),其中尤以后法为优。但后法由于铝碳难以均相混合、铝碳结合性和Al_2O_3反应活性差等原因,氮化合成需要较高的温度和较长的时间,因而 Aluminum nitride (AlN) ceramics have attracted great attention because of their many excellent properties such as high thermal conductivity. As the only way to prepare AlN products, AlN powder is mainly prepared by two methods, that is, Geuther method and Al 2 O 3 carbothermal reduction method (Serpek method). However, after the law due to Al-carbon is difficult to be mixed, aluminum-carbon binding and Al 2 O 3 reactivity and other reasons, nitriding synthesis requires a higher temperature and longer time, and therefore
