METHOD OF OBTAINING HYDROXYAPATITE Russian patent published in 2014 - IPC C01B25/32 C01F11/00 A61K6/33 

FIELD: chemistry.

SUBSTANCE: hydroxyapatite is obtained by mixing 1-1.5% water suspension of calcium carbonate, saturated with carbon dioxide in concentration 1-1.5 g/l, and 1-1.5 water solution of sodium hydroorthophosphate at temperature 20-37°C, with constant mixing and molar ratio CaCO₃/Na₂HPO₄=5-7. The result lies in providing possibility of obtaining hydroxyapatite under harmless for people conditions, under which obtained hydroxyapatite can be used immediately after its obtaining.

EFFECT: method makes it possible to considerably reduce duration of production process.
