Used primarily in the production of lithium-based greases for automotive and industrial applications, where it acts as a key thickening agent. It is also employed in the air purification systems of spacecraft and submarines to remove carbon dioxide from the atmosphere, as it reacts efficiently with CO₂ to form lithium carbonate. Additionally, it serves as a precursor in the synthesis of various lithium salts used in batteries, ceramics, and aluminum processing. Its high alkalinity makes it useful in pH regulation and neutralization processes in chemical manufacturing.
