Explanation

It refers to heat-resistant advanced ceramics materials that can still be used normally under harsh environmental conditions such as over 2000 ° C, mainly including borides, carbide and nitrides of some transition metal elements. They have excellent heat resistance, gasification resistance, ablation resistance and other characteristics, and are key basic materials for key thermal protection systems such as hypersonic missiles and new aerospace vehicles, such as end caps, gas rudders, leading edges of air rudders and engine nozzles.
