Dense materials based on silicon carbide were obtained by liquid-phase sintering. The oxides MgO, Y 2 O 3 and Al 2 O 3 , corresponding to the composition of yttrium-aluminum garnet, were used as a sintering additive. and a triple eutectic point on the line of spinel garnet binary cuts. The oxides were deposited on the surface of the powder by the SiC method of coprecipitation from a salt solution. The maximum density (& # 961; rel = 99.5 & # 37;) is achieved on SiC materials including 20 & # 37; (mass content) of sintering additives of a three-component oxide mixture at a temperature of 1800 & # 176; С
