Chemische Eigenschaften

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).

Chemische Eigenschaften

Calcium peroxide is a grayish-white or yellowish odorless crystalline solid.

Physikalische Eigenschaften

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.

Verwenden

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.

Verwenden

Stabilizer for rubber.

Verwenden

Calcium Peroxide is a dough conditioner which exists as a white or yellowish powder or granule that is insoluble in water. it improves dough strength, grain, and texture, and increases absorption and crumb resiliency. it is used in bakery products.

Allgemeine Beschreibung

A grayish white granular material. Used in baking, in medicine, in bleaching oils.

Air & Water Reaktionen

Isoluble in water and slowly decomposed by water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636].

Reaktivität anzeigen

Calcium peroxide is an explosion hazard if mixed with finely divided organic matter. Noncombustible but accelerates the burning of combustible material: mixtures of combustible material and the peroxide can be ignited by friction or contact with moisture. Mixtures with polysulfide polymers may ignite. Decomposes rapidly above 200° C. Strongly basic Reacts with water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636].

Hazard

Strong oxidizing agent. Dangerous fire risk in contact with organic materials. Irritating in con- centrated form.

Health Hazard

Inhalation of dust irritates nose and throat. Dust also irritates eyes and skin on contact and irritates mouth and stomach if ingested.

Brandgefahr

Behavior in Fire: Can increase severity of fire. Containers may explode.

Sicherheitsprofil

Irritating in concentrated form. Will react with moisture to form slaked lime. Flammable if hot andmixed with finely dwided combustible material. Mixtures with oxiduable materials can also be ignited by grinding and are explosion hazards. A strong alkali. An oxidizer. Mixtures with polysulfide polymers may ignite. See also CALCIUM COMPOUNDS, CALCIUM HYDROXIDE, and PEROXIDES, INORGANIC.

mögliche Exposition

Calcium peroxide is used as a seed disinfectant, an antiseptic, and a rubber stabilizer.

Versand/Shipping

UN1457 Calcium peroxide, Hazard Class: 5.1; Labels: 5.1-Oxidizer

Inkompatibilitäten

Slow reaction with water or other forms of moisture, releasing calcium hydroxide Calcium peroxide is a strong alkali and a strong oxidizer. Incompatible with reducing agents, including hydrides; acids, combustible materials; polysulfide polymers. Rapid decomposition 》200C
