Description
Application
Potassium superoxide is used in rebreathers, submarines, spacecraft, and spacesuits as an oxygen generator. It absorbs carbon dioxide and releases oxygen. Potassium superoxide is used as a CO2 scrubber in rebreathers, submarines, spacecraft, and spacesuits. Potassium superoxide is used as a dehumidifier in rebreathers, submarines, spacecraft, and spacesuits. Potassium superoxide is used in self-contained breathing apparatus that is actuated by the lungs. It supplies oxygen and absorbs carbon dioxide and water.
