Ultra-high temperature ceramics, such as ZrB2, are convenient for application in hypersonic systems due to melting point higher than 3000 °C and excellent ablation resistance. For such application further improvement by addition
of second phases, including SiC or CrB2, has additional benefits in domain of oxidation behavior, while TiB, doping reduces material's weight. A powder mixture of ZrB2, TiB2, CrB, and SiC was high energy ball-mill trough four steps. Obtained milled powder was subjected to hot pressing following different thermal cycles. Subsequent annealing was applied to remove oxide phases and reduce micro-cracking. Due to different thermal treatment, various microstructure and hardness occur. We reached fully dense ceramics, and with different oxide-phases content depending on sintering conditions. Maximal obtained hardness was 24 GPa. Ongoing activity regards the study of the strength and oxidation resistance to assess the suitability of this multi-phase system for hyperso...nic applications.
