Lithium Peroxide Powder Description:

Lithium Peroxide (CAS: 12031-80-0) is the inorganic compound with the formula Li2O2. It is a white, nonhygroscopic solid. Because of its high oxygen: mass and oxygen: volume ratios, the solid has been used to remove CO2 from the atmosphere in spacecraft.

As a worldwide supplier of high-quality Lithium Peroxide, Stanford Advanced Materials (SAM) has over two decades of experience in the manufacture and sale of Lithium Peroxide products.

Lithium Peroxide Powder Applications:

Lithium Peroxide (Li2O2) (CAS: 12031-80-0) is used in air purifiers where weight is important, e.g., spacecraft to absorb carbon dioxide and release oxygen. It absorbs more CO2 than does the same weight of lithium hydroxide and offers the bonus of releasing oxygen. Furthermore, unlike most other alkali metal peroxides, it is not hygroscopic. Lithium peroxide is also used to produce high-purity oxygen. It acts as a catalyst for the polymerization of styrene to polystyrene. Besides, it can serve as a curing agent for special polymers and a source of oxygen in sealed spaces such as submarines and in breathing apparatus.
