Results of a thermodynamic study of 108 phase diagrams of the system Si-O2-C, plotted in the coordinates RT ln pO2-T, are presented. Conditions of the gas medium that intensify SiC synthesis are established. According to the phase diagrams, carbide formation can start at 700 K. The presence of a min...
