Calcium peroxide is a white or yellowish solid peroxide which slowly decomposes to release oxygen at a "controlled" rate when in contact of hydrous media. Calcium peroxide based chemical oxygen product is of the most temperature stable inorganic oxygen release compounds. It decomposes slowly in moist air, is practically insoluble in water, and dissolves in acids, forming hydrogen peroxide.
It is mainly used as an oxidant to enhance the extraction of precious metals from their ores. In its second main application, it is used as a food additive under the E number E930. It is used as flour bleaching agent and improving agent.
In agriculture it is used in the presowing treatments of rice seed. Also, calcium peroxide has found use in the aquaculture to oxygenate and disinfect water. In the ecological restoration industry it is used in the treatment of soils. Calcium peroxide is used in a similar manner to magnesium peroxide for environmental restoration programs. It is used to restore soil and groundwater contaminated with petroleum by the process of enhanced in-situ biremediation.
