A small amount of fine particle graphite was added to $alpha$-SiC and $eta$-SiC having certain particle distributions, and they were mixed clay and frit. After forming, they were sintered at 140$0^{circ}C$ for 3 hours. Tribological properties of sintered $alpha$-SiC-$eta$-SiC-graphite-clay (frit) system showed that kinetic friction coefficient was 0.108, specific wear rate was 1.3${ imes}10^-8;mm^2$.$kgf^1$, and torque was 0.01kgf.cm at the wrench torque of 100 kgf.cm.
