Lithium Chloride: Formula, Properties, Risks and Uses

2020-8-6 · The lithium metal is produced by electrolysis of a molten mixture of lithium and potassium chlorides. The lower melting point of the mixture (400-420 ° C or 750-790 ° F) compared to that of pure lithium chloride (610 ° C or 1 130 ° F) allows the lower temperature operation of the electrolysis .
