鋁熱法是一種利用鋁的還原性獲得高熔點金屬單質(zhì)的方法??珊唵握J為是鋁與某些金屬氧化物(如Fe2O3、Fe3O4、Cr2O3、V2O5等)在高熱條件下發(fā)生的反應(yīng)。鋁熱反應(yīng)常用于冶煉高熔點的金屬,并且它是一個放熱反應(yīng)

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很準的哦!希望你采納我!
一帆杰作
不是每種鹽都可以鋁粉本身就很容易燃燒鋁熱法,又稱鋁熱反應(yīng)(英語:thermite reaction),是用『『鋁粉還原金屬氧化物』』獲得金屬單質(zhì)的方法。反應(yīng)劇烈放熱,溫度可達2500~3500℃,放出耀眼的光芒。生成物為氧化鋁和該高熔點金屬的單質(zhì)。鋁熱劑(thermite)指鋁和金屬氧化物的混合物,一般指鋁和氧化鐵的混合物(比例約為1:2.95)。
