Synthesis and Characterization of Vanadium-Strontium Apatite Type Structures

Scientists atention in compounds with apatite like structures had increased in the last years due to their applications as bioactive materials with high biocompatibility[1,2]. A lot of those compounds, with general formula M 10(XO4)6Y10, had been synthesized by a "chimie douce"method which consists of a precipitation reaction ocurring at a welldefined pH value[3]. In this work a vanadium-strontium apatite was sintetized and next treated thermically at temperatures in the range of 600°C and 800°C. Polycrystals formation in the strontium hidroxiavanadate was confirmed and characterized by Scanning Electron Microscopy (SEM), Transmition Electron Microscopy (TEM), Energy Dispersive Spectroscopy (EDS) and X-Ray difraction tecniques. The SEM microphotographs show multiple aglomerates while de X-Ray spectra shows corresponding apatite phase peaks. © 2009 Microscopy Society of America.
