- Description:
Product Name: Calcium Peroxide
UN NO.: 1457
Molecular Formula: CaO2
Class: 5.1
Molecular weight: 72.07
Quality Standard: GB/T25573-2010
CAS No.: 1305-79-9
- Characteristic:
It is an inorganic compound, the chemical formula is CaO2, it is a light yellow crystalline powder, odorless, almost tasteless, insoluble in water, insoluble in organic solvents such as ethanol and ether, it begins to decompose when heated to 315 ° C, and completely decomposes The temperature is 400～425℃, and the dried product is very stable at room temperature. Calcium peroxide can be dissolved in dilute acid to generate hydrogen peroxide. Calcium peroxide will gradually decompose slowly and slowly in moist air or water, releasing oxygen for a long time.
Because calcium peroxide has the property of releasing oxygen when it encounters water, and it is non-toxic and does not pollute the environment, it is an excellent oxygen supply agent with a wide range of uses. such as aquaculture, crop cultivation, waste water treatment and so on.

- Applications
For environmental protection, calcium peroxide can be used to improve surface water quality, treat heavy metal particle wastewater and control red tide, etc. Oxygen fertilizer and biological compound fertilizer; For aquaculture, it can be used as an oxygen release agent to increase dissolved oxygen in water, adjust the PH value of water, improve water quality, and eliminate pathogenic bacteria. In food processing, calcium peroxide can be used for food, fruit and vegetable preservation, feed additives, dough improvement, food disinfection, etc.; in metallurgical industry, it can be used for dephosphorization and extraction of precious metals; in rubber and chemical industry as natural rubber vulcanizing agent, Polysulfide rubber hardener/sealing agent, unsaturated polyester resin initiator, etc. Calcium peroxide can also be used in the daily chemical industry as tooth cleaners, household disinfectants and deodorants, etc. In addition, calcium peroxide can also be used in emergency oxygen supply, cigarette manufacturing and paint industries.
