High-Temperature Corrosion-Resistant Ceramic Composite Materials Based on (Si-B-C-N) System Compounds (Review)

Systematization of available information on the results achieved in the field of development of promising materials based on two-, three-, and four-component compounds of the (Si-B-C-N) system such as nitrides, carbides, borides, silicon and boron carbonitrides, and silicon borocarbonitride is carried out on the basis of the analysis of domestic and foreign scientific publications. Information about their structure, properties, and methods of obtaining is given. The dependence of the properties of fibers, monoliths, and composite materials on the chemical composition and structure of Si-B-C-N compounds is considered. The results of testing finished products at high temperatures in an oxidizing environment are presented. The prospects of using the materials of the (Si-C-N-B) system in industry and engineering for the manufacture of parts and assemblies designed to work at high temperatures under mechanical loading in aggressive environments are described.
