Abstract
Special features of the component interaction in two groups of SHS systems are investigated: I) oxideoxidizer+oxide-reducer and II) oxide mixtures in which the reaction of formation of a complex oxide is not redox. It is shown that the components of mixtures I first transform into the components of the corresponding mixture II and only after that into the final products. Mass transfer of the reagents in all steps involves eutectic melts as well as gaseous intermediate products whose formation is caused by impurities. Basic macrosteps of the interaction processes of Ba and Sr oxides with WO3 and MoO3 are proposed and confirmed experimentally.
