    Using a set of structural-spectroscopic analysis methods, the relationships between the structure, morphology, and sorption characteristics of samples of nanocrystalline carbonate-substituted calcium hydroxyapatite synthesized with the use of a biogenic source of calcium (avian eggshell) by chemical precipitation from a solution are studied. Using X-ray diffractometry and X-ray microanalysis, impurities are found to enter the structure of the synthesized material from the avian eggshell, which leads to a change in the unitcell parameters of the hydroxyapatite crystal without the formation of additional phosphate phases. Using optical spectroscopy and electron paramagnetic resonance, it is established that, as a result of the inheritance of a set of carbonate-ion impurities, a structure of B-type hydroxyapatite is formed.
