Abstract [eng] |
This study investigates the properties of zinc- and copper-substituted hydroxyapatites, as well as finds the most favorable hydrothermal synthesis conditions. For this purpose, metals-doped hydroxyapatites were obtained by introducing divalent cations (Cu2+ or Zn2+) to the hydrolysis aqueous solutions or by inserting them directly into the structure of the precursor during its synthesis using the wet precipitation method. Hydrolysis reactions were performed in aqueous solutions under hydrothermal conditions (120-230 C; 1-16h). The concentration of the metal ions corresponded to HA substitution levels of 0.1-10.0 mol%. The phase purity, structural properties, morphology, elemental composition, and ion distribution of hydrolysis products were investigated with XRD, FTIR, SEM, ICP-OES and EPR respectively. |
