Abstract: The combustion mechanism and regimes are studied for the mixture Si–C–(–C$_2$F$_4$–)$_n$ Experimental curves are given for dependences of combustion wave parameters for the mixture on the ratio of original components, inert atmosphere pressure, ignition source temperature, and specimen diameter. It is shown that depending on these parameters the process may occur in two steady-state regimes: low-temperature, when there is only formation of silicon fluorides, and high-temperature, when there is successive formation of silicon fluorides and carbides.
