Description

Potassium Superoxide (KO₂) is a powerful inorganic oxidizer and source of oxygen, primarily recognized for its ability to generate oxygen upon reaction with water or carbon dioxide. This property makes it a critical material in specialized closed-system environments where a reliable, on-demand oxygen supply is essential. It is a key component for industrial safety systems, life support applications, and advanced chemical synthesis processes. The compound is identified by the CAS registry number 12030-88-5.

Application

• Emergency Oxygen Generation: Used in rebreathers, mine rescue apparatus, and spacecraft life support systems where it absorbs CO₂ and releases breathable oxygen.
• Industrial Air Purification: Employed in confined spaces and submarines to scrub carbon dioxide from the atmosphere.
• Chemical Synthesis: Serves as a potent oxidizing agent in organic and inorganic chemistry laboratories for specialized reactions.
• Source of Superoxide Ion: Utilized in research and development for generating superoxide radicals in non-aqueous media.
• Pyrotechnics and Incendiaries: Acts as an oxidizer in specific pyrotechnic compositions and ignition mixtures.
• Potassium Peroxide Production: Functions as a precursor in the manufacturing of other potassium-oxygen compounds.

Quality Control

Our Potassium Superoxide is manufactured and tested under stringent quality protocols to ensure high purity and consistent performance. Each batch is analyzed for critical parameters including active oxygen content, moisture, and metallic impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature as a strong oxidizer and being easily oxidized (store under inert atmosphere), it must be stored in a cool, dry, well-ventilated area away from combustible materials, strong acids, and organic solvents. Store under an inert atmosphere such as argon or nitrogen to prevent reaction with moisture and carbon dioxide in the air. Keep container tightly sealed when not in use.
