Applications of Lithium hydroxide

Lithium hydroxide is an asleep admixture with the blueprint LiOH. It is a white hygroscopic apparent material. It is acrid in baptize and hardly acrid in ethanol. It is accessible commercially in anhydrous anatomy and as the monohydrate (LiOH.H2O), both of which are able bases.
Applications
Lithium hydroxide 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 usefulness at both high and low temperatures.
Carbon dioxide scrubbing
Lithium hydroxide is used in breathing gas purification systems for spacecraft (Lithium hydroxide canisters in the Lunar Module and Command/Service Module (after modification) were lifelines for the Apollo 13 astronauts), submarines, and rebreathers to remove carbon dioxide from exhaled gas by producing lithium carbonate and water: 2 LiOH·H2O + CO2 → Li2CO3 + 3 H2O
Or, 2LiOH + CO2 → Li2CO3 + H2O
The latter, anhydrous hydroxide, is preferred for its lower mass and lesser water production for respirator systems in spacecraft. One gram of anhydrous lithium hydroxide can remove 450 cm3 of carbon dioxide gas. The monohydrate loses its water at 100–110 °C.
It is used as a heat transfer medium and as a storage-battery electrolyte. It is also used in ceramics and some Portland cement formulations. Lithium hydroxide (isotopically enriched in lithium-7) is used to alkalize the reactor coolant in pressurized water reactors for corrosion control.
