  • Chromium(II) carbide - Wikipedia

    en.wikipedia.org/wiki/Chromium(II)_carbide Chromium(II) carbide is a ceramic compound that exists in several different 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.
