Abstract

Transparent yttrium aluminum garnet (YAG) ceramics were synthesized by a solid-state reaction method using commercial high-purity ultra-fine powders of α-Al₂O₃ and Y₂O₃ as starting materials. Mixed powders with a molar ratio of α-Al₂O₃ to Y₂O₃, adding 0.5% (in mass) tetralethal ortho silicate as a sintering aid were milled and calcined at 1400°C, then formed and sintered in vacuum at 1750°C for 4 h to obtain the transparent YAG ceramics. Large crystal grain and wide grain boundaries were obtained in YAG ceramics sintered at 1850°C for 4 h, and a eutectic region of yttrium aluminum phase and α-Al₂O₃ existed in the grain boundary.
