The U─Zr─C tertnary phase diagram is optimized by graphical and numerical curve fitting of self‐consistent thermodynamic and phase diagram data reported in the literature. The system is described from 2473 to 3693 K using isothermal ternary phase diagrams. The solidus and liquidus curves of the U x Zr 1−x C y solid solution were estimated from combined thermodynamic and phase diagram data. The solidus and liquidus curves in the ternary system were calculated using a modified form of a free‐energy minimization method developed by Rudy and Chang. The calculated curves agree with experimental data.
