Abstract: New data are obtained on dynamic characteristics of phase formation in the course of alumothermal reaction with participation of melts by using video filming and local pyrometry of the combustion wave of the FeO–Al–Al$_2$O$_3$ powdered system and by studying quenched products. The capillary mechanism of convective processes at the stages of reactive conversion, segregation of the oxide and metal melts, and formation of the porous product of interaction is studied.

Keywords: alumothermal reaction, heterogeneous systems, melts, capillary convection, combustion, phase formation.
