Abstract

A novel calcium-silicate based bioactive glass composition containing dysprosium and iron was prepared following the sol-gel route. According to thermal analysis results, the heat treatment temperatures were selected at 500 oC, 800 oC and 1200 oC. The paper reports results obtained by X-ray diffraction, surface area and pore analysis, and UV-Vis spectroscopy with respect to the structural changes induced by these thermal treatments..
