Lithium Hydroxide Properties

Lithium Hydroxide



Lithium hydroxide is an inorganic compound. It is mainly consumed for the production of lithium greases. A popular lithium grease is lithium stearate, which is a general purpose lubricating grease due to its high resistance to water and being useful at both high and low temperatures. Lithium hydroxide is used in breathing gas purification systems for spacecraft, submarines, and rebreathers to remove carbon dioxide from exhaled gas by producing lithium carbonate and water. It is used as a heat transfer medium, as a storage-battery electrolyte. It is also used in ceramics and some Portland cement formulations. Lithium hydroxide is used to alkalize the reactor coolant in pressurized water reactors for corrosion control.
