After the thermite reaction triggered a spontaneous response, short reaction time, can not control, becauseThe required ingredients accurate (calculation and weighing), mixing evenly, so as to avoid segregation furnace charge很准的哦!希望你采纳我!
Aluminum is a trigger spontaneous thermal reaction, short reaction time, can control, becauseAnd accurate calculation and ingredients (weighing), mixture evenly, lest cause burden segregation
