First principle modeling and calculations of hydroxyapatite both native and surface modified and having various defects (OH vacancies, H inter-nodes) were performed. Local Density Approximation method used with calculations of Density of States allows us to analyze the experimental obtained work function data. Molecular modeling was confirmed by photo-electron measurements up to 6.5 eV and photoluminescence experimental data from synchrotron DESY up to 30 eV. Brief analysis of the influence of heating, microwave radiation, hydrogenation, and synchrotron radiation on hydroxyapatite surface is presented in this work. New data on the structure of modified hydroxyapatite are obtained.

“…Nano-sized HAP powders doped with Sr and Mn ions were synthesized by modified precipitation methods, based on the chemical interaction between calcium hydroxide and phosphoric acid, as most suitable method for the synthesis of nano-sized HAP powders [24,33,34]. Strontium and manganese ions were added into the starting solutions in order to substitute calcium ions in the HAP structure, in different forms and in different percents (according to the optimal literature data) [7][8][9]21].…”

The influence of Sr and Mn incorporated ions on the properties of microwave single- and two-step sintered biphasic HAP/TCP bioceramics

et al. 2014

The aims of this study were to investigate the effects of Sr-and Mn-doped ions on the sintering behaviors, microstructure and mechanical properties of the bioceramics processed by single-and two-step microwave sintering (MWSSS and MWTSS). Nano-sized calcium hydroxyapatite powders doped with Sr and Mn ions, obtained by modified precipitation synthesis, were isostatically pressed at 400 MPa and processed by MWSSS and MWTSS at different temperatures. In all cases during the sintering, the doped HAP powders turned into biphasic mixtures of HAP and TCP, but the amount of TCP was certainly lower in the case of MWTSS. It was shown that the doped ions significantly affected: density, microstructure, grain size, porosity, hardness, and fracture toughness of the processed bioceramics. Two-step microwave sintering was successfully applied for the processing of HAP/ TCP bioceramics doped with strontium and manganese ions. Both two-step microwave sintered doped bioceramics had similar and high hardness values, but the strontiumsubstituted bioceramic material certainly had higher fracture toughness (1.54 MPam 1/2 ), with an average grain size of 195 nm. Based on the results presented in this paper, it was concluded that the two-step microwave sintered strontium-doped bioceramics could be suitable materials in the bone regenerative field.
