摘要
报道了铝电解质添加氯化钠 (NaCl)对于物理化学性质的影响 ,其主要优点是降低电解质的熔点 ,提高导电性 ,减少铝的溶解损失量 ,因而提高电流效率。此外 ,氯化钠的价格低廉可以降低铝的生产成本。当NaCl添加量少于3%时 ,水解反应较弱 ,并无不良影响 ,其优点可与添加LiF相提并论。
This paper reports the influence of additive NaCl to the physical chemical properties of aluminium electrolte.The main advantages are:⑴ decreasing the melting point of electrolyte,⑵ increasing its electrical conductivity,⑶ decreasing the metal solubility hence increasing the current effictiencr.In addition,the price of NaCl is low,and can reduce the production cost of aluminium.The merits of NaCl are nearly equal to that of LiF.When the amount of addition of NaCl is iower than 3% there will be much less hydroscopicity effect of NaCl.
