Abstract
Nanocrystalline hydroxyapatites were prepared by the precipitation method using a water soluble Ca2+ organic compounds and (NH4)2HPO4. The fine nanohydroxyapatites had spherical, needle-like or mixed morphology and specific areas around 150 m2/g. The nanocrystalline powders differed by thermal stability and they were transformed to bi- or three-phasic systems with hydroxyapatite, βTCP and αTCP phases after annealing at 1000 °C.
► Preparation of nanohydroxyapatite without utilisation of toxic organic substances. ► No additional thermal treatment is needed for removing undesirable residues. ► Organic residues from ligands of Ca2+ compounds are feasible for living organism.
