The thermodynamic potentials of binary TiB2–SiC, B4C–SiC, and B4C–TiB2 systems are constructed with the pseudopotential method. The energy of thermal oscillations is calculated using Einstein's model and the energy of interaction between atomic planes. The mixing energy of the systems is calculated to confirm that the eutectic is formed. The minimum thermodynamic potential is used to determine the eutectic temperatures and concentrations of the components.
