Uses & manufacturing
General Manufacturing InformationSulfuric acid, lithium salt (1:2): ACTIVE
Applications
UsesLithium sulfate is used in making a special type of high strength glass. It also is used in medicine as an antidepressant.
UsesLithium sulfate, anhydrous is used to treat bipolar disorder, solar panels and the potential for a new class of battery, and used as a catalyst for the elimination reaction.
Preparation methods
PreparationLithium sulfate is prepared by neutralization of lithium hydroxide or lithium carbonate with sulfuric acid followed by crystallization: 2LiOH + H2SO4 → Li2SO4 + H2O Li2CO3 + H2SO4 → Li2SO4 + CO2 + H2O The product obtained from crystallization in a concentrated solution is the monohydrate, Li2SO4•H2O. Anhydrous salt is obtained by heating the monohydrate in a vacuum.
PreparationIndustrially lithium sulfate and its monohydrate are prepared by the same basic procedure. Lithium sulfate monohydrate is isolated by evaporation of a solution of lithium sulfate made by the reaction of sulfuric acid with either lithium hydroxide or lithium carbonate. The lithium sulfate monohydrate may be converted to anhydrous lithium sulfate by drying at slightly over 100°C.
