Abstract

Dense ZrB₂-SiC ultra-high temperature ceramics were prepared by a novel pressureless sintering process. the relative density of sintered ceramics increased from 62.5% for ZrB2 to 96.7% by coating the starting ZrB₂ powder with polycarbosilane, which was converted to C and SiC by pyrolysis. the mechanism of enhanced densification and the mechanical properties of the sintered ZrB₂-SiC ceramics were investigated.
