電(dian)(dian)解鋁(lv)就是(shi)通過電(dian)(dian)解得到(dao)的鋁(lv)。現代電(dian)(dian)解鋁(lv)工業生產采用(yong)冰晶石(shi)(shi)-氧(yang)化鋁(lv)融鹽(yan)電(dian)(dian)解法。熔融冰晶石(shi)(shi)是(shi)溶(rong)劑，氧(yang)化鋁(lv)作(zuo)為溶(rong)質，以碳素(su)體作(zuo)為陽極，鋁(lv)液作(zuo)為陰極，通入強大的直流(liu)電(dian)(dian)后，在(zai)950℃-970℃下，在(zai)電(dian)(dian)解槽(cao)內的兩(liang)極上進行(xing)電(dian)(dian)化學反(fan)應，既電(dian)(dian)解。
