Sintering of silicon carbide obtained by combustion synthesis

[EN] An activated combustion synthesis method was utilized to synthesize silicon carbide from the elementary mixture in the presence of polytetrafluoroethylene (PTFE) as a thermochemical promoter and product's morphology modifier. Thermodynamic calculations in the initial Si–C-(C2F4)n mixture r...
