Plutonium carbide comes in several

stoichiometries Stoichiometry refers to the relationship between the quantities of reactants and products before, during, and following chemical reactions. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals ...

(PuC and Pu₂C₃). It can be used as a nuclear fuel for nuclear reactors in conjunction with

uranium carbide Uranium carbide, a carbide of uranium, is a hard refractory ceramic material. It comes in several stoichiometries (''x'' differs in ), such as uranium methanide (UC, CAS number 12070-09-6), uranium sesquicarbide (U2C3, CAS number 12076-62-9), a ...

. The mixture is also labeled as uranium-plutonium carbide (UPuC).
