Visualization of the Reaction Zone Spreading for an Alumothermic (Redox) Reaction

Liljana Stefanovska, Toma Grcev, Sonja Gegovska-Zajkova

Redox reactions between small solid particles (Me1/Me2 ? oxide) are very fast exothermic and autocatalytical reactions, which take place at the solid/liquid interface. An attempt to correlate the experimentally obtained data for the alumothermic (Al/Fe3O4) reaction with several mathematical (geometrical) models for reaction zone spreading was made in this paper.
