摘要: 以Y(NO3)3和NH3·H2O为原料,并在Y(NO3)3溶液中添加少量(NH4)2SO4,采用沉淀法制备出化学组成为Y2(OH)5(NO3nH2O的先驱沉淀物.先驱沉淀物在1100℃下煅烧4h,得到了平均粒径为60nm的氧化钇原料粉体.Y2O3粉体与Al2O3、Nd2O3超细粉球磨混合后,采用固相反应工艺,经1700℃真空烧结5h,制备出透明的Nd:YAG陶瓷,同时对Nd:YAG透明陶瓷的光学性能进行了研究.

Abstract: Y2(OH)5(N03nH2O precursor was produced using Y(NO3)3 solution containing small amount of ammonia sulfate and NH3·H2O solution. Yttria powders (60nm in average size) were obtained by calcining the precursor at 1100℃ for 4h. The Y2O3, Al2O3 and Nd2O3 powders were mixed by ball milling, and then sintered into a fully transparent Nd:YAG ceramic body by vacuum sintering at 1700℃ for 4h by a solid-state reaction method. The optical properties of the transparent Nd:YAG ceramic was investigated.

Key words: YAG, transparent ceramics, solid-state reaction, optical properties
