Abstract

The glasses in the SrO-TiO2-P2O5 system were prepared by the conventional quenching route. The amorphous state of samples was verified by X-ray diffraction (XRD). Density, molar volume, micro-hardness, glass transition temperature (Tg), and crystallization temperature (Tc) parameters are determined for each glass. The results show that they depend strongly on the chemical compositions. The structure approach of the glasses is determined by using Infrared spectroscopy (IR). This investigation highlights that the glassy-matrix contains various phosphate structural units. The crystallization of the glasses by heat-treatments is performed and the crystallized phases Sr3P 4O13, TiP2O7, Sr(PO 3)2 are identified by XRD. The overall results are correlated to the glass structure and the nature of chemical bonds constituting the glass network. © 2012 Elsevier Ltd.
