Used primarily in the production of lithium greases, which are valued for their high-temperature stability and water resistance, making them ideal for automotive and industrial lubrication. It serves as a precursor in the synthesis of various lithium-based chemicals used in batteries, ceramics, and glass. In aerospace and confined environments like submarines and space capsules, it acts as a carbon dioxide absorbent due to its ability to react with CO₂, helping maintain breathable air. Also utilized in the processing of aluminum oxide and in certain types of alkaline batteries.
