Description and Uses

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. It occur abundantly in nature in several forms and are the principal minerals for the production of phosphate fertilizers and for a range of phosphorus compounds. For example, the tribasic variety (precipitated calcium phosphate), Ca3(PO4)2, is the principal inorganic constituent of bone ash. The acid salt Ca(H2PO4)2, produced by treating mineral phosphates with sulfuric acid, is employed as a plant food and stabilizer for plastics. It is a natural constituent of mammals, and it is a component of bone replacement transplants in much higher amounts with no toxicological problems.

Calcium phosphates are the largest group of artificial bone graft substitutes. This is mainly due to their close resemblance to the mineral components of bone. This Product can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra-226) and strontium (Sr-90) in the gastrointestinal (GI) tract.
