Abstract
The paper reports results from experimental studies of the combustion of ilmenite- and quartz-based powder mixtures and formation of products in the combustion reactions. The reaction regimes involving the formation of porous microheterogeneous compositions Al2O3–metal-like alloy were studied. It is shown that the mechanisms of hot-spot combustion and formation of an anisotropic macrostructure of the reaction products are interrelated. Key words: combustion, hot-spot reaction, minerals, ceramics.
