摘　　要：重点研究了氧化铝陶瓷注射成型中热塑性粘结剂的选取和对应的热脱脂工艺。结果表明,当Al_2O_3粉料质量百分含量为70%、选用石蜡/聚丙烯/硬脂酸(m_(PW):m_(PP):m_(SA)=79:20:1)热塑性粘结剂时,采用适当的热脱脂工艺,可获得结构缺陷少、性能较高的Al_2O_3陶瓷材料。In this paper,the choice of thermoplastic binder and corresponding debinding technology for alumina ceramic injection molding are mainly discussed. The results show that the Al2O3 mass content should be 70% in the loading powders and the thermoplastic binders are PW/PP/SA （mpw：mpp：mSA=79 ： 20 ： 1）. And the alumina ceramic with few structure defects and excellent performances could be obtained when the appropriate debinding technology is adopted.
