Key Points

This research aims to investigate how replacing silicon dioxide with aluminum and barium oxides affects the properties of alkali-free silicate glasses.
Examined glasses with varying ratios of SiO2, Al2O3, and BaO.
Analyzed elemental and phase compositions using various spectroscopy and microscopy techniques.
Measured thermal properties through differential scanning calorimetry and dilatometry.
Assessed structural properties with Raman and infrared spectroscopy.
No significant changes were observed in the glass structure or structure-sensitive properties.
The coefficients of linear thermal expansion and glass transition temperatures remained relatively stable.
Heat treatment showed crystal formation dependent on the glass composition and temperature.
