Uses and synthesis of Calcium phosphate powder

Calcium phosphate powder, Chemical structure This product is a mixture of different forms of calcium phosphate. White crystal or amorphous powder. Insoluble in ethanol and acetone, slightly soluble in water, easily soluble in dilute hydrochloric acid and nitric acid. Calcium phosphate can be used as an anti-aggregation agent, acidity regulator, nutrient supplement, flavor enhancer, stabilizer, and water retention agent. Mainly used in polystyrene, styrene-acrylonitrile, expandable polystyrene polymer cooperative dispersant, as well as ceramics, biological materials, fluorescent materials and so on. Calcium phosphate is also used in the manufacture of ceramics, stained glass, and emulsion glass. It can be used as dental binder, plastic stabilizer, polishing powder, syrup clarifying agent, chemical fertilizer. Also used in rubber and printing industries.

Applications/Functions of Calcium phosphate powder

1. Calcium phosphate powder is used as an anti-caking agent, nutrient supplement (calcium strengthening), and flavor enhancer. As an anti-caking agent, China stipulates that it can be used for solid drinks, and the maximum usage is 8.0g/kg; Can also be used for wheat flour, the maximum use of 0.03g/kg. It can also be used as nutrient fortifier, Ph regulator and buffer.
2. Calcium phosphate is mainly used in polystyrene, styrene-acrylonitrile, expandable polystyrene polycooperative dispersants, as well as ceramics, biomaterials, and fluorescent materials. Also used in the manufacture of ceramics, colored glass, emulsion glass. It can be used as dental binder, plastic stabilizer, polishing powder, syrup clarifying agent, chemical fertilizer. Also used in rubber and printing industries.
3. Calcium phosphate is used as a feed additive of poultry, which promotes digestion of feed and increases the weight of poultry. At the same time can also treat livestock rickets, osteomalacia and so on.

Physicochemical Property of Calcium phosphate powder

Calcium phosphate White crystal or amorphous powder. Slightly soluble in water (solubility 0.0025g/100ml water), easily soluble in dilute hydrochloric acid and nitric acid, insoluble in ethanol and acetone.

Production methodprocess of Calcium phosphate powder

By adding food grade phosphate solution to saturated lime milk, tricalcium phosphate precipitation (controlling CaO/P2O5=3) was generated, Calcium phosphate powder was obtained by filtration, washing and drying.
