Abstract

The characteristics of advanced ultra-high temperature ceramics (UHTCs), such as strength at high temperature and oxidation resistance, allow them to be used in extreme environments including those associated with hypersonic flight, atmospheric re-entry and rocket propulsion. ZrB₂+εvol.%SiC ceramic composites were prepared by hot-pressing in a flowing argon atmosphere with AlN as a sintering aid in this paper. Compared with additive free ZrB ₂, the doping of aluminium nitride as a sintering aid greatly improves the powder sinterability of zirconium diboride and nearly full dense composites were obtained by hot pressing. The mechanical properties were enhanced remarkably through these improvements in the sinterability and microstructure. The relation between sintering aid and sintering dynamics of ZrB₂ based UHTCs was investigated. The microstructures of the ceramic composites were investigated by SEM, EDS et.al. Mechanical and high temperature ablation resistant properties of the ceramic composites were tested using oxyacetylene facility.
