Using quantum-mechanical calculations on the basis of an a priori pseudopotential, it is proved that B4C−SiC is a partial quasibinary eutectic system, where a number of insolubles (B4C, SiC) contain carbon, which is linked to a change of the stoichiometric composition of B4C at high temperatures (B12C3 → B13C2).

Keywords: pseudopotential, quasi-coherent, stoichiometric composition
