摘　　要：采用机械力化学法制备YAG粉体,探讨分散剂添加量、球磨时间和矿化剂的用量对反应的影响,并对烧结产物的性能进行研究。结果表明:分散剂加入量不宜过多,最佳用量为每50 g原料混合物加入10mL分散剂;随球磨时间的延长,样品平均粒度先减小再增大,得到最佳粒径的球磨时间为60min;分别加入矿化剂5.53%(质量分数,下同)AlF3和5.55%(质量分数,下同)NH4F时,完全生成了纯相的YAG;采用矿化剂AlF3制备的YAG粉体的烧结活性优于加入NH4F制备的YAG粉体。Effect of dosage of disperser, ball milling time and the percentage of the mineralizer on YAG powders prepared by mechano-chemical approach as well as the sintering properties were investigated in this article. The results show that too much dosage of disperser is not suitable, the best dosage is 10 mL. The average size of the particle decrease first and then increase with the extension of grinding time. The appropriate ball milling time is 60min. The pure YAG can be obtained by adding mineralizer A1F3 of 5.53% or NH4F of 5.55%. In addition, the sintering activity of the YAG powders obtained by AIF3 is better than that by NH4F.
