Mechanism for the Formation of a Solid Solution of Carbon in Silicon Carbide

Abstract

We consider a mechanism for the formation of a solid solution of carbon in silicon carbide when various carbide synthesis methods are used that involve participation of thermally expanded (exfoliated) graphite. We have determined the role of chemical transport reactions in processes of solid-phase interaction between the components of the synthesis. We have optimized the conditions for synthesis of a powder of a solid solution of carbon in silicon carbide with participation of thermally expanded graphite.
