Usage

Description

Lithium sulfate is a metal sulfate in which the counterion is lithium and the ratio of lithium to sulfate is 2:1. It is a colorless monoclinic or hexagonal crystalline solid and is the lithium salt of sulfuric acid. It has a role as an antidepressant and contains a lithium(1+). It is used in various applications, including the production of high-strength glass, medicine, and as a catalyst for the elimination reaction.

Uses

1. Used in Glass Manufacturing:
Lithium sulfate is used as a strengthening agent for the chemical strengthening of glass. It is used in small quantities in molten salt baths to enhance the strength of the glass produced.
2. Used in Medicine:
Lithium sulfate is used as an antidepressant in the treatment of mood disorders, such as bipolar disorder. It helps in stabilizing mood swings and managing depressive episodes.
3. Used in Solar Panels and Battery Technology:
Lithium sulfate, anhydrous, is used in the development of solar panels and has the potential for a new class of battery, contributing to advancements in renewable energy and energy storage technologies.
4. Used as a Catalyst:
Lithium sulfate is used as a catalyst for the elimination reaction, a chemical process that involves the removal of a molecule from a larger molecule, leading to the formation of a smaller molecule.
5. Conversion to Lithium Carbonate:
The dissolved lithium sulfate can be converted into lithium carbonate by adding sodium carbonate (NaCO3). The sodium replaces the lithium in the sulfate compound, and this reaction works because sodium is more reactive than lithium. This conversion process is useful in the production of lithium carbonate, which has various applications in the pharmaceutical, chemical, and battery industries.

Preparation

Industrially 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.

Flammability and Explosibility

Nonflammable

Purification Methods

Crystallise it from H2O (4mL/g) by partial evaporation, and dry it above 130o in vacuo.
