Abstract

The high strength of oxide eutectic composites is not lost near 1500°C. The synthesis of a eutectic composite is carried out by unidirectional solidification. This solidification is inadequate to produce large and near-net-shaped materials. Eutectic powders of Al₂O₃-Y₃Al₅O₁₂(YAG), Al₂O₃-GdAlO₃ were prepared from the eutectic composite melted by arc discharge and high-frequency induction heating. The powder was classified into 3-44, 44-64 and 64-124μm, and consolidated by the spark plasma system (SPS).
