Presented are the analysis of physical and mechanical properties of the Al2O3, SiC and Si3N4 matrix ceramics with additives of good electrical conductivity phases and TiB2 matrix ceramics. The density, Young’s modulus, hardness HV1 and electrical conductivity of each material were investigated. Ceramic composite materials with the participation of the conductive phases have been produced using SPS (spark plasma sintering) method. Materials characterized by good electrical conductivity were shaped using EDM (electro discharge machining) method.
