Importance of defect nanocrystalline calcium hydroxyapatite characteristics for developing the dental biomimetic composites

Popis výsledku v původním jazyce

Applying a set of structural-spectroscopic methods of analysis we have studied the relationships between the structure, morphology and sorption characteristics of the samples of nanocrystalline carbonate-substituted hydroxyapatite (C-HAP) synthesized with the use of biogenic calcium source (poultry eggshell) obtained by the chemical deposition from a solution. With the use of X-ray diffractometry and X-ray microanalysis it was found that the appearance of impurities in the structure of synthesized material was due to their presence in calcium carbonate of the poultry eggshell and this could result in the changes of parameters in the elementary crystal cell of hydroxyapatite without formation of the additional phosphate phases. Optical and ESR spectroscopy allowed us to find that in the presence of the inherited set of impurities inclusion of carbonate ions into the structure of our synthesized hydroxyapatite takes place with the formation of C-HAP of B-type.
