Calcium peroxide Chemical Properties,Uses,Production
Description
Calcium peroxide is a grayish-white or yellowish odorless crystalline solid. Molecular weight=72.1;Freezing/Melting point=275℃ (decomposes). HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 0, Reactivity 1. Insoluble in water.Chemical Properties
Calcium peroxide is a grayish-white or yellowish odorless crystalline solid.Chemical Properties
White or yellowish powder; odorless; almost tasteless. Decomposes at approximately 200C. Almost insoluble in water; soluble in acids with formation of hydrogen peroxide. Available oxygen 22.2% (min 13.3% in technical grade).Physical properties
For all practical purposes, calcium peroxide is insoluble in water but will dissolve in acid to form H2O2. When in contact with water, it will immediately begin to decompose releasing oxygen.Uses
Stabilizer for rubber.Uses
Calcium peroxide is an ecologically pure substance
that has been used in various fields of industry and
agriculture.
In environmental protection, it is used:
? For treating wastewater and remediation of
groundwater
? For decontaminating soil
In agriculture, it is used:
? As a fertilizer rich with oxygen
? For stimulating seed growth and their germination
capability
? For presowing treatment of rice seed, which allows to
do planting not by seedlings, but by dry seeds, coated
with calcium peroxide. Such a technique sufficiently
decreases the work expenditure and increases crop
capacity.
In aquaculture, it is used:
? To provide sufficient dissolved oxygen
? To adjust pH value
? To reduce the subaqueous content of ammonium and
nitrogen
? To eliminate carbon dioxide and sulfureted hydrogen
? To prevent anaerobic bacteria from proliferation and
application to manure heaps to kill disease-carrying
bacteria originating from animal defecation.
In poultry raising, it is used:
? To decontamination of fodder
? To increase productivity, safety from disease in hens
and improving their eggs.
In cattle breeding, it is used:
? For prophylaxis of casein-stone formation in the
abdomen and to prevent diarrhea with newborn
calves
? As an antimicrobic agent to prevent disease
? For stimulating protective organism strength
? For normalizing activity of the alimentary canal
? For activating digestion work
? For great increasing live-stock safety.
In the bakery industry, it is used:
? To improve bread crumb and its porosity
? To keep moisture in dough during its baking
? To initiate yeast growth.
