Preparation and characterization of some substituted bioglasses and their ceramic derivatives from the system SiO2–Na2O–CaO–P2O5 and effect of gamma irradiation

Glasses having chemical composition based on Henchʹs bioglass® and with some substituted oxides were prepared and crystallized through thermal treatments. These glasses and corresponding glass–ceramics were characterized by Fourier transform infrared spectroscopy (FTIR) either through absorption or reflection studies. Chemical corrosion of the prepared glassy and crystalline samples as grains was examined by the action of 0.1 M HCl or NaOH solutions or by distilled water. Also, UV–vis absorption measurements were carried out before and after successive gamma rays to reveal their response to ionizing radiation.
