SiC/TiC laminar ceramic composites were fabricated using electrophoretic deposition (EPD) from acetone‐based suspensions. The growth rate of the SiC was almost twice that of the TiC at the same deposition voltage and solids loading. Pressureless sintering and spark plasma sintering (SPS) of the composites were investigated. SiC in the composites without sintering additives could not be densified using pressureless sintering, even at 2000°C. SPS, however, could densify the SiC/TiC composites at 1800°C and 35 MPa. The relative density of the SPS sample was 98.9%.
