Generally, the washing step is important in the precipitation method to remove the residuals in solution and to stabilize the phase …

Pharmacodynamics. Calcium phosphate reacts with acid in the stomach to raise the pH 3. In toothpaste it provides a source of calcium and phosphate ions to support remineralization of the teeth 1. As a supplement it provides a source of calcium and phospate, both of which are important ions in bone homeostasis. Mechanism of action.

In this study, we develop an integrated process for the direct recovery and separation of dicalcium phosphate dihydrate for fertilizer and livestock feed additive production from a low-grade (2.0 wt% P) iron-rich (19.7 wt% Fe) phosphate ore. The process combines leaching using dilute sulfuric acid (0.29 M) and selective precipitation using ...

Until now, two different forms of crystalline CaPs with a Ca/P atomic ratio of 1:1 have been documented: CaHPO4·2H2O (brushite; dicalcium phosphate dihydrate, DCPD) and CaHPO4 (monetite ...

Preparation and characterization of DCPM. Amorphous calcium hydrogen phosphate (ACHP), with a Ca/P atomic ratio of 1.0 38, which is identical to that of DCPM, was used as a precursor for the crystallization of DCPM (see Methods section for details).The amorphous character of its precursor was confirmed by X-ray powder …

Dicalcium phosphate dihydrate (DCPD) was hydrolysed in water and in 1 M Na2HPO4 solution at temperatures from 25–60°C. Hydrolysis was incomplete in water. At 25 °C, DCPD partially hydrolysed to hydroxyapatite (HAp). Formation of HAp is indicative of incongruent DCPD dissolution. At the higher temperatures, hydrolysis to HAp was more …
