Study of the dependence of the structural defects and bulk inhomogeneities of nanocrystalline hydroxyapatite on the conditions of production using a biological source of calcium

Popis výsledku v původním jazyce

The study of structural and bulk defects in nanocrystalline samples of hydroxyapatite with a developed surface was carried out. The XRD method established distortions in the crystal lattice of the synthesized samples of hydroxyapatite (HAP), which are associated with the inclusion of impurity atoms present in the eggshell of birds used as a biological source of calcium. The presence of impurity atoms of magnesium, sodium, and fluorine in the obtained materials was determined by X-ray photoelectron spectroscopy. Applying ESR and Raman spectroscopy it was found the presence of CO3 complex in the structure. Studies of the morphological organization of the samples found a large number of surface defects – nanopores – in crystalline HAP. At the same time, the size of these 3D defects depends on the conditions of preparation and is determined by the content of phosphate groups in the initial solution.n
