Abstract
Abstract For this study, we investigated the effect of V2O5 and ZnO on crystallization of zirconia fiber-reinforced BaO-CaO-SiO2 glasses with Al2O3, B2O3, V2O5, and ZnO additions. Differential scanning calorimetry measurements were performed to study crystallization behavior. Additionally, experiments were performed on pressed glass pellets and drops of molten glass. The specimens were heat-treated at different temperatures for different dwell times and finally quenched. The microstructure was analyzed for a cross section of the samples using scanning electron microscopy and the chemical composition was characterized using energy-dispersive X-ray spectroscopy. Combined with high-temperature X-ray diffraction measurements, it was possible to identify the predominant crystalline phases: binary barium silicates, walstromite, celsian, and itsiite.
