C/C composites have excellent performance in an inert atmosphere, but poor oxidation resistance. C/SiC composites have the characteristics of low density, oxidation resistance, and excellent
mechanical properties, but the maximum operating temperature does not exceed 2000°C .

Boron-containing Lithium ion battery electrolyte additive

Carbide ultra-high temperature ceramics mainly include zirconium carbide (ZrC), tantalum carbide (TaC) and hafnium carbide (HfC).

nano-HfB2--Hafnium diboride

physical properties of metal zirconium

The refractory diborides (HfB2 and ZrB2) are considered as promising ultra-high temperature ceramic (UHTCs) where low damage tolerance limits their application for the thermal protection system in re-entry vehicles.
