Bone Apatite - an overview | ScienceDirect Topics

A Ca–Fe phosphate phase approaching that of calcioferrite (Ca 4 Mg(Fe 3+) 4 (PO 4) 6 (OH) 4.12H 2 O) has been reported by Jenkins (1994) in archaeological cave sediments. It was found in the form of orange-brown coatings and infillings of voids, where it formed by translocation of phosphate colloids derived from the dissolution of bone apatite.

Which Minerals Include Phosphate? - ThoughtCo

Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine; silicon, arsenic or vanadium replace the phosphorus (and carbonate replace the phosphate group); and strontium, lead, and other elements substitute for the ...

Jan 17, 2018· As fluoride is known to affect the biomineralization of calcium phosphates, we examined how the growth at 37 °C of octacalcium phosphate (OCP) and hydroxyapatite (HAp) on an amorphous calcium phosphate substrate is affected by low-dose fluoride (0–2 ppm) in metastable calcium phosphate solution. In the absence of fluoride, highly oriented plate-like OCP crystals grow on the …

Apatite - Wikipedia

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
