電(dian)(dian)解(jie)鋁就是通過電(dian)(dian)解(jie)得到的(de)鋁。現(xian)代電(dian)(dian)解(jie)鋁工業生產采用冰晶石-氧化鋁融(rong)(rong)鹽(yan)電(dian)(dian)解(jie)法。熔融(rong)(rong)冰晶石是溶(rong)劑，氧化鋁作(zuo)為(wei)(wei)溶(rong)質(zhi)，以碳素體(ti)作(zuo)為(wei)(wei)陽極，鋁液(ye)作(zuo)為(wei)(wei)陰(yin)極，通入強大(da)的(de)直流電(dian)(dian)后，在950℃-970℃下，在電(dian)(dian)解(jie)槽內的(de)兩極上進行電(dian)(dian)化學反應，既電(dian)(dian)解(jie)。
