Аннотация: The hydroxyapatite powders with co-doping of Ca2+ with Na+ and Ce3+ were obtained by aqueous precipitation. Co-doping was considered as a method of charge compensation in the cationic sublattice of the HA structure by means of the 2Ca2+→Ce3++Me+ in order to maintain the stability of phase composition, improve the optical and microstructural properties of the HA ceramics. The content of dopants ranged from 0.25 to 1.0 mol. % relative to calcium atoms in HA. The ceramics were obtained by traditional sintering in an air atmosphere and by hot pressing under soft reducing conditions in order to trace Ce oxidizing in HA matrix. Phase and chemical composition of the obtained ceramics were investigated using powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), and atomic emission spectrometry with inductively coupled plasma (AES-ICP). Microstructure and microhardness were estimated in order to trace the dopant effect on the ceramic formation. Luminescence spectra were recorded to evaluate the content of cerium ions in the Ce3+ state and to reveal the dopant effect on structure features of the HA.
