Chromium(II) carbide - Wikipedia

Chromium(II) carbide is a ceramic compound that exists in several chemical compositions: Cr 3 C 2, Cr 7 C 3, and Cr 23 C 6.At standard conditions it exists as a gray solid. It is extremely hard and corrosion resistant. It is also a refractory compound, which means that it retains its strength at high temperatures as well. These properties make it useful as an additive to metal alloys.
