In this study, the addition of SiO2 additives to SiC ceramics was carried out to reduce the sintering temperature by producing optimal ceramics. The addition of SiO2 was given as much as 0, 0.5, 1 and 1.5 (mass%). The additives were weighed, mixed and ground using High Energy Milling for 30 minutes. Then it was sintered at temperatures of 850°C, 1000℃ and 1100°C. The characterization results showed that the composition of 1.5% SiO2 at 1100°C had a density of 2.835 g/cm3 and a porosity of 11.1% and a hardness of 876.7 Hv. From XRD analysis, only two phases were identified, namely moissanite (SiC) and cristobalite (SiO2). The crystal size decreased with the addition of SiO2 additives, but the sample of 1.5% SiO2 at a temperature of 850°C occurred agglomeration so that the crystal size was getting bigger. The shape and size of the grains in ceramics are irregular from one grain to another. Through an image with a magnification of 5000x the particle size of SiC-SiO2, it is obtained about 1 μm to 7 μm
