May 01, 1925 Full Text. Abstract. In adult bony tissues the matrix in which the bone cells are embedded appears as a clear homogeneous mass, giving no visible indication of the large amounts of calcium carbonate and phosphate which are contained in it, although these salts form two thirds of its mass. The only visible evidence of the presence of these salts is to be found in newly forming, very rapidly …

Calcium phosphate | Ca3(PO4)2 - PubChem

Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent 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 in the gastrointestinal (GI) tract.
