摘要

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 (T_g), and crystallization temperature (T_c) 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 Sr₃P₄O₁₃, TiP₂O₇, Sr(PO₃)₂ are identified by XRD. The overall results are correlated to the glass structure and the nature of chemical bonds constituting the glass network.
