Abstract
The combustion of the SiO2–Al(Zr)–C system is studied near the extinction limit. Temperature distribution over the combustion zone is obtained using the thermocouple procedure. It is shown that in combustion of samples with diameter not exceeding 8 mm, thermal losses give rise to a temperature gradient over a section of the sample, which transforms the thermal structure of the combustion wave and leads to inhomogeneity of the end product. New data on the formation mechanism of the reaction products are given.
