Composite ceramics of granular silicon carbide, precipitation hardened by eutectic additives of the Al 2 O 3 -MnO-TiO 2 system, have been obtained. The effect of a dispersed eutectic powder in the Al 2 O 3 -MnO-TiO 2 system is considered depending on the ratio of silicon carbide / eutectic additive: 99/1 , 97/3 and 95/5 and pressing pressure on the sintering performance of a ceramic matrix composite based on granular silicon carbide. It was found that after firing at 1350 & # 176; C and a pressing pressure of 200 MPa with the introduction of 5 & # 37; (mass content) of the eutectic additive of composition A or B, the porosity is 5.6 and 4.1 & # 37; and the flexural strength reaches 65 & # 177; 5 and 85 & # 177; 5 MPa respectively
