• Tongbaite - Wikipedia

    en.wikipedia.org/wiki/Tongbaite Tongbaite is a rare mineral that has the chemical formula Cr 3 C 2, or chromium carbide.. It was first described in 1983 for an occurrence in Liu village, Tongbai County (桐柏县), Henan Province, China and named for the locality. It occurs in an ultramafic rock deposit. It has also been reported from the Tibet Autonomous Region and from the Isovsky District in the Urals of Russia.

  • Chromium(II) carbide - Wikipedia

    en.wikipedia.org/wiki/Chromium(II)_carbide 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.
