• THE SAFETY OF DICALCIUM PHOSPHATE PRECIPITATED FROM

    The typical dicalcium phosphate manufacturing process includes first a degreasing step of fine crushed bones in hot water (80° to 85°C). Regularly shaking removes a high percentage of proteins. The dried stone chips then undergo a demineralisation process: they are submitted over a total period of 4-5 days, to a sequence of solutions

    Dicalcium-Phosphates- Process, Technology, Applications

    Dicalcium phosphate Wikipedia

    Dicalcium phosphate is the calcium phosphate with the formula CaHPO4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO4 anion involves the removal of two protons from phosphoric acid, H3PO4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate. Dicalcium phosphate is used as a stone additive, it is found in some toothpastes as a polishing agent and is a biomaterial.

    Calcium Phosphate Solubility: The Need for Re-Evaluation

    In addition, contrary to wide belief, dicalcium phosphate dihydrate (DCPD) is not the most stable phase below pH ∼4.2, where calcium-deficient HAp is less soluble. The misunderstanding here arises from the metastability of DCPD, which nucleates much more easily than HAp at low pH. Such results indicate that the Ca−P system is in need of complete reappraisal. The solid-titration method can
