Abstract

ZrB₂-20 vol.% SiC ceramic containing 10 vol.% graphite flake and 10 vol.% SiC whiskers (ZSGS) was fabricated by hot pressing. The mechanical properties and thermal shock resistance of the ZSGS ceramic were investigated. The results revealed that thermal shock resistance and fracture toughness were significantly improved, whereas slight degradation was attained in the flexural strength of the ZSGS ceramic. Furthermore, the effect of the thermal conductivity, toughness and strength on the thermal shock resistance of the ZSGS ceramic was also investigated and discussed.
