Other compositions are available, eg. Cr23C6 (occurring as extremely rare mineral isovite, cubic) and Cr7C3.
Chromium carbide is used as a thermal spray material for protecting the underlying metal surface, and as an additive to corrosion-resistant and wear-resistant materials. It is used in coatings of bearings, seals, orifices, and valve seals, and as a fine-crystal phase in other sintered carbides, where, like the vanadium carbide, it inhibits growth of submicrometre grains during pressing and sintering. It is highly corrosion-resistant, and does not oxidize even at high temperature (1000-1100 °C). The powder for coating costs $40-$65 per pound.
