Lithium Chloride

Lithium Chloride (LiCl) is an ionic compound or salt that is highly polar and soluble in water. It is more soluble in organic solvents such as acetone and methanol than potassium chloride or sodium chloride. Lithium chloride is widely used in several industrial applications.

Lithium chloride is a chemical compound with the formula LiCl. The salt is a typical ionic compound (with certain covalent characteristics), although the small size of the Li+ ion gives rise to properties not seen for other alkali metal chlorides, such as extraordinary solubility in polar solvents.

Lithium chloride application

Electrochemistry

Lithium metal is produced by electrolysis of lithium chloride and potassium chloride, which melts at 450°C. High-purity lithium chloride is used as the feedstock in the process and makes about 99.5% pure lithium metal.

Molten lithium is contained in a carbon steel pot, while the chlorine gas is collected in a stainless steel or glass pipe for applications in other processes. The molten lithium flows into a collecting tank and is later cast into ingots. A mesh or stainless-steel screen separates the two compartments to prevent the products from mixing.

Other Applications of Lithium Chloride

It is used as a flame colorant to form dark crimson flames. It is used in the precipitation of RNA in biological applications. It is an aluminum blazing flux in automobile parts. It is used for several soldering and welding techniques and salt bath heat treatment at low temperatures. Lithium chloride is used in massive dehumidification systems in the AC industry. This depends on the low equilibrium pressure of vapor above lithium chloride solutions.
