Enhanced Densification and Mechanical Properties of ZrB₂-SiC Processed by a Preceramic Polymer Coating Route
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.
