Abstract:
The aim of this research was the synthesis of hydroxyapatite powders of the
(Ca10(PO4)6(OH)2) type by a precipitation method with the following synthesis conditions:
the ratio of Ca/P = 1, pH 7). Another main target of this work was a partial substitution
of calcium in the hydroxyapatite structure with selected doping elements (magnesium,
zinc, aluminium, strontium) with the subsequent assessment of the effect of such
replacements on the structure and physicochemical properties of hydroxyapatite. The
synthesized powders were characterized by X-ray diffraction (XRD), in order to identify
the phase composition and crystallinity, and by scanning electron microscopy (SEM) to
study the morphology of synthesized powder. Finally, to define the anticorrosive
purposes, preliminary corrosion tests were also performed.
