摘　　要：以β-Si3N4粉末为原料,MgAl2O4为烧结助剂,通过气氛压力烧结(GPS)制备出致密的β-氮化硅陶瓷材料,探讨了β-氮化硅陶瓷烧结机制,系统研究了烧结助剂质量分数、烧结温度以及保温时间对材料致密化的影响。Dense silicon nitride ceramics were obtained from β-Si3N4 powder with MgAl2O4 as sintering additives through gas pressure sintering (GPS).The properties of sintering were discussed and the effect of sintering temperature and holding time and additives content on the densification of β-Si3N4 ceramics were studied systematically.
