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
