Abstract
Tetragonal ZrO2-SiC whisker composite powders have been synthesized by the sol-gel method. Analysis reveals that SiC whiskers are homogeneously dispersed in the composite powder, the matrix being ultrafine metastable tetragonal ZrO2. The sintering properties of the composite have been investigated. SiC whiskers favour an increase in content of metastable tetragonal ZrO2. When the SiC whisker content is high, the critical stress intensity factor (KIC) decreases.
