Abstract
Stoichiometric calcium hydroxyapatite was synthesized from aqueuos solutions of calcium and
phosphorus salts. Composition and structure of the HAp and its natural analogues were determined by
XRD analysis, FTIR spectroscopy, electron microscopy and thermogravimetric analysis. As was shown,
natural apatites are characterized not only by presence of carbonate groups in their structure, but by
comprisal of diphosphate groups, oxygen and fluorine. It was determined that there is trace impurity of
iron, strontium, sodium and potassium in the natural apatites. In the current paper results of determination
of the structural, spectroscopic and thermal characteristics of the HAp and its natural analogues are
shown
