Ultra-high-temperature ceramics refer to a class of ceramic materials that have a high melting point above 3000°C and have excellent high-temperature oxidation resistance, ablation resistance and thermal shock resistance, mainly boron compounds of IV B, VB group transition metals, Carbide and its composite materials. At present, ultra-high temperature ceramics still have good oxidation resistance when the temperature reaches 1600℃.
Potential application
Ultra-high temperature ceramic materials are mainly used for thermal protection systems of hypersonic missiles, space shuttles and other aircraft such as wing leading edges, end caps and hot ends of engines. They are alternatives to refractory metals and one of the most promising materials in the ultra-high temperature field One.
