In this article it is established that the physical and mechanical characteristics of reaction-sintered silicon carbide ceramics are directly sensitive not only to the parameters of structure fault detection, but also to the totality of the homogeneity of the distribution of all components in the volume of the material, which largely determines the technological parameters of the molding ceramic powders.

Theoretical calculations of the residual silicon content in the structure of reaction-sintered silicon carbide are provided. The dependence of the bending strength on the initial carbon content is established experimentally. The rational fractional composition and amount of the carbon component are determined to obtain silicon carbide ceramics with maximum increased strength. [ABSTRACT FROM AUTHOR]

High-density silicon carbide ceramic materials with enhanced physical and mechanical characteristics are obtained by selecting the particle size of the furnace charge and reactive sintering (siliciding). Various mechanical properties of silicon carbide materials are analyzed depending on the content of the core silicon carbide fiber. [ABSTRACT FROM AUTHOR]
