In a given work, the morphological and physicochemical properties of calcium hydroxyapatite powders obtained by varying the temperature synthesis parameters are investigated, using atomic force microscopy, IR spectroscopy, and NMR methods. The features of the morphology of calcium hydroxyapatite nanoparticles’ formation by varying the annealing temperature in the range of 200–1000?C are determined. As shown, the particle size of the apatite obtained by annealing at 700?C is about 40 nm and corresponds to the particle size of the native bone apatite. As revealed, the influence of size effect on the structural parameters of calcium hydroxyapatite manifests itself in a higher local symmetry of PO43? tetrahedra for nanodispersed calcium hydroxyapatite.
