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%.

机械化处理天然砂和铝粉混合物中的热爆炸

探索了机械化学处理（MCT）对天然砂与铝粉的压实共混物在各种条件下，是否存在改性剂（石墨和聚乙烯醇）的条件下进行MCT的压实混合物中热爆炸的影响。发现在改性剂存在下的MCT显着提高了热爆炸的最高温度，缩短了诱导期，并稳定了燃烧过程。在最佳条件下，铝的消耗量达到了96.9％。
