Product Description

Calcium Peroxide (CaO₂) 

Synonyms: Calcium dioxide, Calcium superoxide, Peroxycalcite

 

1. Chemical Identification

• CAS Number: 1305-79-9
• Formula: CaO₂
• Molecular Weight: 72.08 g/mol
• Hazard Class: Oxidizing agent (UN 1457, Class 5.1)

 

2. Physical Properties

• Appearance: White or yellowish powder/granules.
• Odor: Odorless.
• Melting Point: Decomposes at ~200°C (releases oxygen).
• Density: ~2.9 g/cm³.
• Solubility: Sparingly soluble in water (reacts slowly to release oxygen and form calcium hydroxide).

 

3. Chemical Properties

• Oxidizing Agent: Releases oxygen upon decomposition or reaction with water/acid.
• Reactivity:
  • Reacts with acids to produce hydrogen peroxide (e.g., CaO₂ + H₂SO₄ → CaSO₄ + H₂O₂).
  • Stable under dry conditions but decomposes in humid environments.
• pH (in water): Alkaline (forms Ca(OH)₂).

 

4. Applications

• Agriculture: Oxygen source for soil remediation and seed coatings.
• Environmental: Used in bioremediation and wastewater treatment to oxygenate anaerobic systems.
• Dental: Component in some tooth-whitening products.
• Food Industry: Dough conditioner (E930, approved in some regions).
• Industrial: Oxidizer in pyrotechnics and specialty cement formulations.

 

5. Safety & Handling

• Hazards:
  • Oxidizer: Can intensify fires; incompatible with combustible/organic materials.
  • Skin/Eye Irritant: Causes irritation on contact.
  • Inhalation: Dust may irritate respiratory tract.
• Protective Measures:
  • Use gloves, goggles, and dust masks.
  • Store in a cool, dry, well-ventilated area away from reductants and acids.
• First Aid:
  • Skin/Eyes: Flush with water for 15 minutes.
  • Ingestion/Inhalation: Seek medical attention.

 

6. Storage & Disposal

• Storage: Keep in airtight containers, away from moisture and heat.
• Disposal: Follow local regulations for oxidizing agents. Neutralize with water and dispose of as non-hazardous waste if fully decomposed.

 

7. Environmental Impact

• Low toxicity but may release oxygen in aquatic systems, affecting pH and dissolved oxygen levels.

 

8. Regulatory Information

• EU: Classified as oxidizing (H272).
• US OSHA: Regulated as a hazardous oxidizer.
• Transport: UN 1457, Class 5.1.

 

9. Key Notes

• Calcium peroxide decomposes to calcium hydroxide and oxygen:
  2CaO₂ + 2H₂O → 2Ca(OH)₂+ O₂↑
• Avoid contact with strong acids or reducing agents (e.g., sulfur, phosphorus).
