Applications

Agriculture and Soil Improvement

  • Calcium Peroxide is widely used for soil oxygenation and crop growth enhancement. When it comes into contact with moisture, it slowly releases oxygen and calcium hydroxide, improving soil aeration and promoting root development. It revitalizes acidic or anaerobic soils and boosts microbial activity in the rhizosphere.
  • In rice and aquatic crop systems, Calcium Peroxide prevents root rot and enhances germination by providing a steady oxygen supply under flooded conditions. It is also incorporated into controlled-release fertilizers as both an oxygen donor and a pH buffer, improving nutrient availability and plant uptake efficiency.

Environmental Protection and Waste Treatment

  • Calcium Peroxide is employed in in-situ chemical oxidation processes for the remediation of contaminated soil and groundwater. It acts as a solid oxygen source that decomposes to form hydrogen peroxide and oxygen, oxidizing organic pollutants such as hydrocarbons, phenols, and pesticides.
  • In industrial and municipal wastewater treatment, Calcium Peroxide enhances biological degradation efficiency by maintaining aerobic conditions and reducing odor formation. It is also used in anaerobic sludge control to minimize sulfide and ammonia emissions.

Food and Feed Industry

  • In food applications, Calcium Peroxide functions as a flour-bleaching and dough-improving agent, enhancing dough elasticity and whiteness. It is approved in many countries as a food-grade processing aid within regulated limits.
  • In animal feed, Calcium Peroxide serves as an oxygen releaser and antibacterial additive, helping to preserve feed freshness and suppress microbial growth during storage.

Aquaculture and Water Treatment

  • Calcium Peroxide is used extensively in fish farming and pond management as a slow oxygen-generation agent. It releases oxygen steadily into the water, increasing dissolved-oxygen levels and sustaining healthy aquatic ecosystems. It also decomposes organic sediments on pond bottoms, preventing fish mortality caused by hypoxia.
  • In combination with magnesium or iron compounds, Calcium Peroxide helps control algae growth and reduce ammonia and nitrite accumulation, maintaining balanced water quality for aquaculture operations.

Chemical and Industrial Applications

  • Calcium Peroxide serves as a controlled oxygen source and oxidizing agent in the production of percarbonates, perborates, and other peroxide derivatives. It is utilized as a catalyst component and stabilizer in various synthetic reactions that require gentle oxidation.
  • It plays an auxiliary role in rubber vulcanization and polymer modification by releasing oxygen to support crosslinking reactions. Additionally, Calcium Peroxide is used for detoxifying cyanide solutions in the mining industry and for paper-pulp bleaching as a clean alternative to chlorine oxidants.

New and Emerging Applications

  • Recent developments highlight Calcium Peroxide’s use in bioremediation nanocomposites, slow-release oxygen carriers for medical and aquatic systems, and energy-storage or oxidative-technology materials. Its gradual oxygen-release capability makes it ideal for controlled-environment systems demanding safe and sustained oxygen delivery.

Storage & Handling

  • Store in a dry, well-ventilated place away from heat and moisture.
  • Keep containers tightly sealed and prevent contact with acids or reducing substances.
  • Avoid direct sunlight and ensure storage temperature remains stable.
  • Handle using non-sparking tools and follow standard peroxide safety procedures.
