摘要：

By means of the conventional quenching route, the glass series 33Na(2)O-xSrO-xTiO(2)-(50 - 2x)B2O3-17P(2)O(5) (x = 0-12.5 mol%) were prepared. 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 Infrared spectroscopy (IR). This investigation highlights that the glassy-matrix contains various phosphate and borate structural units. The crystallization of the high-TiO2 glasses by heat-treatments favors the formation of titanate phosphate Na4TiO(PO4)(2) or Sr0.5Ti2(PO4)(3) along with Sr-3(PO4)(2) inside the glass-matrix.
