摘要
We report that the Al 2 O 3 [sbnd]Y 2 O 3 ceramic composites with eutectic composition can be flash sintered at 1250 °C under the applied electrical field of 550 V/cm in an extremely short time (30 s). The solid-state reactions between Al 2 O 3 and Y 2 O 3 facilitate the flash sintering process. The sintered Al 2 O 3 [sbnd]YAG ceramic composites exhibit relatively high hardness and high fracture toughness. These results demonstrate the feasibility of employing the flash sintering technique to fabricate oxide ceramic composites.
