High-entropy carbide-nitrides with enhanced toughness and sinterability

High-entropy ceramics (HECs) have attracted much attention due to their huge composition space, unique microstructure, and desirable properties. In contrast to previous studies, which have primarily focused on HECs with one anion, herein, we report a new family of ceramics with both multi-cationic and -anionic structures, i.e., high-entropy carbide-nitrides (Ti0.33Zr0.33Hf0.33)(C0.5N0.5), (Ti0.25Zr0.25Hf0.25Nb0.25)(C0.5N0.5) and...
