The dependences of the microstructure and physical-mechanical properties of Si3N4–TiN-based ceramic in a wide range of mass ratios of the components are examined. The sintering process and the accompanying physical and chemical processes, viz. the dependence of the hardness and density of the material on the ratios of the conducting phase of titanium nitride and the dielectric phase of silicon nitride with values above and below the percolation threshold, are examined. A ceramic based on pure titanium nitride with high physical-mechanical characteristics (H = 21.5 GPa) is obtained.
