Atomic force microscopy, infrared spectroscopy and NMR studied morphological and physicochemical properties of calcium hydroxyapatite powders produced by changing the temperature parameters of synthesis. Features of morphology formation of calcium hydroxyapatite nanoparticles with an annealing temperature within 200A degrees C to 1,100A degrees C were determined. It is shown that the particle size of the apatite obtained that annealed 700A degrees C is 40 nm corresponding to the particle size of apatite in native bone. The effect of dimension factor on structural parameters of calcium hydroxyapatite is manifested in a more local symmetry of the PO4 (3-) tetrahedra at nanodispersed calcium hydroxyapatite.
