Abstract: In this work, we describe the synthesis of the MAX-phase of titanium silicon carbide (Ti₃SiC₂) received by the method of self-propagating high-temperature synthesis (SHS) with application of pressure (SHS-pressing). Compacted Ti₃SiC₂ was obtained from initial mixture of powders of titanium, silicon and carbon (soot) with the ratio of powder components of 3Ti+(1.2-1.25)Si+2C. Using X-ray diffraction, scanning electron microscopy and energy dispersive analysis, it was shown that the synthesized product of SHS-pressing is a dense composite material consisting of the core phase of Ti₃SiC₂ and side phases of TiC and TiSi₂. The basic physical and mechanical properties of the new composite material: density, compressive strength, hardness, electrical conductivity were studied. This material is of interest as a promising electric contact material.
