摘　　要：Transparent Nd：YAG/YAG composite ceramics are synthesized by solid-state reaction method using high- purity Y203, A1203, and Nd203 powders as raw materials. The mixed powder compacts are sintered at 1780 ℃ for 10 h under vacuum and annealed at 1450 ~C for 20 h in air. The Nd：YAG/YAG ceramics exhibit a pore free structure with an average grain size of about 30 μm. The microstructure of the Nd：YAG/YAG composite transparent ceramics is studied and there is no interface between Nd：YAG and YAG ceramics. The Nd ion distribution in one grain is also studied, which shows that there is no segregation of Nd ions as in Nd：YAG crystals.Transparent Nd：YAG/YAG composite ceramics are synthesized by solid-state reaction method using high- purity Y203, A1203, and Nd203 powders as raw materials.
