以自制Y2(SO4)3和NH4Al(SO4)2·12H2O混合溶液为母盐,碳酸氢铵为沉淀剂,采用共沉淀法制备了以YAG相为主要成分的混合粉体.研究表明,先驱体化学成分为[NH4AlO(OH)HCO3]·0.3[Y2(CO3)3·2H2O].先驱体经1200℃、2h煅烧,pH=7.2时产物以YAG相为混合粉体的主要成分,pH=8.5时Y2O3为主要成分.在较低温度下(低于1500℃),以硫酸盐为母盐制备的YAG混合粉体烧结性低于同样条件下硝酸盐为母盐合成的粉体烧结性.1100℃煅烧2h后合成的YAG混合粉体(pH=7.2),经1700℃真空烧结5h,获得了完全透明的YAG陶瓷,可见光区的最大透光率约为60%.
