A composite ceramic was obtained from granular silicon carbide dispersion-hardened with eutectic additives of the system Al2O3–MnO–TiO2 was obtained. The influence of the dispersed powder of the eutectic in system Al2O3–MnO–TiO2 on the sintering indicators of the ceramic matrix composite based on the granular silicon carbide was studied as a function of the silicon-carbide/eutectic-additive ratio 99/1, 97/3, and 95/5 and the pressing pressure. It was determined that after firing at 1350°C and pressing under pressure 200 MPa with introduction of 5% (weight content) eutectic additive with composition A or B the porosity is equal to 5.6 and 4.1%; the strength in bending reaches 65 ± 5 and 85 ± 5 MPa, respectively.
