Preparation and Characteristics of B2O3 – SiO2 – Bi2O3 – TiO2 – Y2O3 Glasses and Glass-Ceramics

The method of melting – quenching used for the manufacturing of investigated glasses. Aim of the study is to learn about and comprehend the structural, thermal, and crystallization features of these glasses. The method of X-ray diffraction was originally used to check the status of manufacture samples. Molar volume was decreased while density was raised in this investigation. Fourier transform infrared investigated showed that as Y2O3 replaced by TiO2. Bridging oxygens (BOs) increment, while non-bridging oxygens (NBOs) reduce, enhancing the structural units and interconnection. Differential thermal analysis was used to examine these glasses’ thermal stability. The thermal stability enhanced as Y2O3 concentration increased. The glass-ceramic was created using controlled heat and analysed using X-ray diffraction and scanning electron microscope. Glass-ceramic samples’ ultrasonic velocities and elastic moduli enhance as internal energy rises. The Y2O3 modifier’s effect on the glass system has been established.
