铝热法是一种利用铝的还原性获得高熔点金属单质的方法。可简单认为是铝与某些金属氧化物(如Fe2O3、Fe3O4、Cr2O3、V2O5等)在高热条件下发生的反应。铝热反应常用于冶炼高熔点的金属,并且它是一个放热反应

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!
一帆杰作
不是每种盐都可以铝粉本身就很容易燃烧铝热法,又称铝热反应(英语:thermite reaction),是用『『铝粉还原金属氧化物』』获得金属单质的方法。反应剧烈放热,温度可达2500~3500℃,放出耀眼的光芒。生成物为氧化铝和该高熔点金属的单质。铝热剂(thermite)指铝和金属氧化物的混合物,一般指铝和氧化铁的混合物(比例约为1:2.95)。
