Abstract

The effect of various additives such as TiB₂, HfB₂, CrB₂, TaB, TaSi₂, LaB₆, La₂O ₃, and AlN on the oxidation behavior of ZrB₂-based ultra-high-temperature ceramics (UHTCs) at 1800°C was investigated. The additions of CrB₂ and HfB₂ to the ZrB₂-SiC composites have minor effect on the structure evolution of the oxide scale and oxidation resistance. However, all the other additives, especially for Ti and Ta compounds, have changed the oxidation mechanism resulting in a marked detrimental effect on the oxidation resistance of ZrB₂-based UHTCs.
