Used as a desiccant for drying gases due to its strong hygroscopic nature. Commonly employed in air conditioning systems for humidity control. Serves as an electrolyte in certain types of batteries and electrochemical cells. Utilized in the production of lithium metal through molten salt electrolysis. Applied in biological research for precipitation of RNA and in cell culture protocols. Also used in the ceramics industry to modify thermal expansion properties and in welding fluxes to improve conductivity and arc stability.
