Abstract

SiC whisker-reinforced ZrO₂ composite is prepared by flash sintering. The density of the composite obtained at the optimal conditions is close to the theoretical value. SEM observations reveal that the whiskers with well-preserved original morphology are uniformly distributed within the matrix and strongly bonded with ZrO₂. The composite exhibits a fracture toughness value higher than SiC-ZrO₂ (with 6 mol% Y₂O₃) made by conventional hot-pressing. These results clearly demonstrate that the flash-sintering can prepare SiC_w/ZrO₂ composites more effectively.
