Abstract
In this study, high-temperature composite materials based on reactively sintered silicon carbide modified with a molybdenum bond are obtained. The microstructure, phase composition, and physico-mechanical properties of the formed composites are determined. It is experimentally shown that molybdenum in the process of reaction sintering forms a stable MoSi2 phase with a silicon melt in the volume of the sintered ceramic material. It is shown that the numerical parameters of lacunarity and chaos allow us to evaluate the homogeneity of the material structure in a direct relationship with the variation of the technological modes of ceramic synthesis. The resulting composites are characterized by a density of about 3.02–3.16 g/cm3 and a bending strength of about 180–220 MPa.
