Zirconium carbide specimens containing significant quantities of dissolved oxygen were synthesized using ZrO 2 and graphite as reactants in an atmosphere of CO. These specimens were studied by X‐ray diffraction and analyzed chemically for C, O, and Zr. The data indicate that oxygen substitutes in the ZrC lattice, replacing more than 1 C atom/O atom, thus decreasing the lattice parameter. Under the conditions of the study, the reaction product is a solution of oxygen in the ZrC phase rather than a distinct oxycarbide phase.
