Hydroxyapatite can be synthesized via several methods, such as wet chemical deposition, biomimetic deposition, sol-gel route (wet-chemical … 展开

Calcium-deficient (non-stochiometric) hydroxyapatite, Ca10−x(PO4)6−x(HPO4)x(OH)2−x (where x is between 0 and 1) has a Ca/P ratio between 1.67 and 1.5. The Ca/P ratio is often used in the discussion of calcium phosphate phases. … 展开

Along with its medical applications, hydroxyapatite is also used in downstream applications under mixed-mode chromatography in polishing step. The ions present on the surface of hydroxyapatite make it an ideal candidate with unique selectivity, … 展开

Due to its high biocompatibility, bioactivity, osteoconductive and/or osteoinductive capacity, nontoxicity, nonimmunogenic properties, and noninflammatory behavior, hydroxyapatite is available and used as a bone filler and as coatings on prostheses. Designing bone … 展开

Mammals (including humans)
Hydroxyapatite is present in bones and teeth; bone is made primarily of HA crystals interspersed in a collagen matrix—65 to 70% of the … 展开

As of 2019 , the use of hydroxyapatite, or its synthetically manufactured form, nano-hydroxyapatite, is not yet common practice. Some studies suggest it is useful in counteracting dentine … 展开

In archaeology, hydroxyapatite from human and animal remains can be analysed to reconstruct ancient diets, migrations and … 展开
