Abstract
Abstract Novel glass-ceramics of the nominal molar compositions 20Fe2O3·20B2O3·(60-x)V2O5· (xNa2O or xSrO) (where x = 0 or 10) were prepared by traditional melt technique. Differential thermal analysis (DTA) was implemented to study the thermal behavior of the prepared glasses. Vanadium pentoxide (V2O5), iron vanadate (FeVO4), sodium vanadate (Na3VO4) and strontium vanadate (with different formulae) were crystallized and identified by X-ray diffraction (XRD) analysis under certain conditions of heat-treatment. Further characterization of glass and glass ceramics samples were performed using scanning electron microscope (SEM), density, electrical and dielectric measurements. In conclusion, our study elucidated that the substitution of vanadium by Na+ and Sr2+ ions enhanced the conductivity at 180 °C from 5.11 × 10−4 for unmodified glass to 2.93 × 10−3 and 1.03 × 10−2 S cm−1 for Na- and Sr-modified glasses.
