导言铝电解工业采用氟化锂改良电解质不是什么新创举。实际上,Charles Hall在他早先的专利中对使用氟化锂作了一般性的申述。当今,已普遍公认氟化锂改良电解质具有所希望的性质。由于熔盐中锂离子迁移率高,所以冰晶石电解质的电导率随着添加氟化锂而增 Introduction The use of lithium fluoride in the aluminum electrolysis industry to improve the electrolyte is not a new initiative. In fact, Charles Hall made a general statement of his use of lithium fluoride in his earlier patent. Today, it is generally accepted that lithium fluoride modified electrolytes have the desired properties. Due to the high lithium ion mobility in the molten salt, the conductivity of the cryolite electrolyte increases with the addition of lithium fluoride
