摘　　要：采用注浆成型和真空烧结制备了Nd：YAG激光透明陶瓷,研究了烧结温度和时间对致密化过程的影响。研究结果表明：在1050～1300℃之间坯体发生明显的收缩生成YAM和YAP相;在1300～1420℃,生成YAG相。随着烧结温度的增加,陶瓷中气孔含量减少,晶粒尺寸长大。在1700～1800℃烧结20h能够获得完全致密的Nd：YAG陶瓷样品。Dense Nd：YAG transparent ceramic was obtained by slip casting and vacuum sintering.The effect of sintered temperature and dwell time on the densification and microstructure development of Nd：YAG transparent ceramics were investigated.The YAP and YAM formation appeared from 1050℃ up to 1300℃,resulting in a significant densification.YAG was obtained in the vicinity of 1400℃,whereas beyond 1400℃,no other phase was detected.The densification and grain size increased with the increasing of the sintered temperature.Pore free Nd：YAG transparent ceramic with a grain size of 5μm to 10μm was obtained between 1700℃and 1800℃sintering for 20h.
