冰晶石成份是氧化鋁~
在化學角度如果降低電解鋁時的溶點??
點解在電解鋁的時候要加入冰晶石~~

✔ 最佳答案
冰晶石的成份是Na3AlF6, 不是氧化鋁電解氧化鋁時加入冰晶石的原因是減低混合物的溶點
氧化鋁的溶點高達攝氏二千度
加入冰晶石後電解槽可在攝氏九百多度運作
大大減低成本

because the rate of reaction of electrolysis of Al is too slow.
in order to increase the rate, a catalyst is used.
and the aluminium oxide is one of the catalyst to this reaction.
