Abstract

The influence of mechanochemical treatment (MCT) on thermal explosion in compacted blends of natural sand with Al powder subjected to MCT under varied conditions in the presence/absence of modifying agents—graphite and polyvinyl alcohol—was explored. MCT in the presence of modifiers was found to markedly increase a maximum temperature of thermal explosion, to shorten the induction period, and to stabilize the combustion process. Under optimized conditions, the extent of Al consumption attained a value of 96.9%.
