Lithium Chloride is a highly hygroscopic inorganic salt available in anhydrous or solution form. It is one of the most soluble salts known, particularly in polar organic solvents and water. This Technical Grade material is critical for the production of lithium metal via electrolysis. It also serves as a high-performance desiccant due to its ability to absorb large quantities of atmospheric moisture. In specialized industrial sectors, it is used as a brazing flux for aluminum and as an electrolyte component. Its stability and high purity ensure consistent performance in energy storage technologies.

SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers Lithium Chloride (CAS 7447-41-8) to customers in more than 40 countries.
