Fabrication of Transparent Nd:YAG Ceramics by a Solid-State Reaction Method

Sun Xu

Abstract

Y2(OH)5(N03)·nH2O 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.
