· Cr3B4

Cr3B4 is a chromium boride ceramic compound that combines the hardness and refractory properties of boride ceramics with chromium's oxidation resistance. This material belongs to the family of transition metal borides and is of primary research and developmental interest rather than widespread industrial production, though it shows promise for high-temperature and wear-resistant applications where conventional carbides may fall short.
