N2 - In this study, B4C/SiC composites containing different amounts of SiC were produced by reactive spark plasma sintering of B4C, SiO2 and C powder mixture. The sintering process was carried out at 1700°C and 1750°C and under 40 MPa pressure for 5 minutes in a vacuum by using Dr. Sinter SPS. After the sintering process, the phase formation in the samples was determined by an X-ray diffraction technique. The variation in density, hardness, fracture toughness, flextural strength and microstructure of samples were investigated. The highest relative density and hardness value is, respectively, 99,7% and 35 GPa, obtained by the sample containing 5 vol.% SiC at 1750°C for 5 minutes in a vacuum atmosphere. It was also found the highest flextural strength by the sample containing 5 vol.% SiC at 1700°C for 5 minutes.
