Bone is continually hydroxyapatite is not fully known, it is assumed to be similar to that of collagen; approximately 10 years.

The stoichiometry of bone mineral basically is that of hydroxyapatite precipitating from phosphate, calcium, and water at a slightly alkaline pH:

The ultrasonically assisted synthesis ( sono-synthesis ) of hydroxyapatite is a successful technique to produce nanostructured hydroxyapatite at high quality standards.

Hydroxyapatite ( Calcitite ) and other mineral bone analogues are used in bone grafting applications, but not primarily for their physical properties.

Tetracalcium phosphate is a component used in the formation of some hydroxyapatite calcium phosphate cements that used for the repair of bone defects.
47.
Calcium acts structurally as supporting material in bones as calcium hydroxyapatite ( Ca 10 ( PO 4 ) 6 ( OH ) 2 ).
48.
It binds collagen and hydroxyapatite in separate domains, is found in relatively large amounts in immature bone, and promotes mineralization of collagen.
49.
It was also observed that quartz and metallic silver crystallization increased with the increase in silver content in bioactive glass while hydroxyapatite crystallization decreased.
50.
Sintering these non-stoichiometric phases forms a solid phase which is an intimate mixture of tricalcium phosphate and hydroxyapatite, termed biphasic calcium phosphate:
