Quaternary glasses with Y2O3 addition were synthesized and studied, showing increased optical bandgap, refractive index, and thermal parameter values. Y2O3 acted as an excellent nucleating agent, promoting crystallization and supporting the formation of glass-ceramics.
Quaternary glasses with the composition 50SiO(2) - 25TiO(2) - 5La(2)O(3) - (20-x) Na2O - xY(2)O(3) where x : (0 <= x >= 10) were synthesized using the melt-quench technique. XRD examined the nature of prepared glasses. UV-spectroscopic of investigated glass system studied at room temperature. Both optical bandgap and refractive index of the present glass have been increased. The polarizability and basicity were determined. Thermal parameter values increased as Y2O3 increased. Under controlling heat, the glass-ceramic were prepared and confirmed using XRD. Glass-ceramics are examined using SEM to evaluate a microstructure. Ultrasonic velocities and elastic-moduli of glass-ceramic samples are increased because of the increase in internal energy. The role of Y2O3 modifier in the glass system is clearly demonstrated. Y2O3 also works as an excellent nucleating agent that can induce crystallizations, supporting in the creation of the sub-phase of glass-ceramics.
