The oxidation behavior of four ZrB₂-SiC-ZrC compositions with varying ZrC contents (20, 34, 50, and 64 vol.%) was compared to that of ZrB₂-SiC. The ceramics were oxidized at 1700 °C in an oxygen-hydrogen torch environment. The liquid oxide on the ZrB₂-SiC sample came off from the surface under such an environment. In contrast, the all ZrB₂-SiC-ZrC samples maintained the convex oxide on the surface, which consisted of ZrO₂ and SiO₂. The convex oxide of ZSZ with higher ZrC content was thicker, with the exception of ZrB₂-SiC-64vol.%ZrC sample. The ZrB₂-SiC-64vol.%ZrC sample formed a ZrO₂-rich layer, which was clearly denser than the ZrO₂-SiO₂. This densification was caused by ZrO₂-sintering, and it was specific behavior under the dynamic pressure.

四个的ZrB氧化行为₂ -SiC-的ZrC组合物具有不同的ZrC内容（20，34，50，和64体积％）中的溶液相比的ZrB的₂ -SiC。在氧气-氢气炬环境中，将陶瓷在1700°C的温度下氧化。在这种环境下，ZrB ₂ -SiC样品上的液态氧化物从表面脱落。相反，所有ZrB ₂ -SiC-ZrC样品均在表面上保留了由ZrO ₂和SiO ₂组成的凸形氧化物。ZrC含量较高的ZSZ凸氧化物较厚，但ZrB ₂ -SiC-64vol。％ZrC样品除外。ZrB ₂ -SiC-64vol。％ZrC样品形成ZrO ₂层，显然比ZrO ₂ -SiO ₂致密。该致密化是由ZrO ₂烧结引起的，并且是在动态压力下的特定行为。
