Analysis of Physical and Structural Properties of Alkali Oxide–Modified Tellurite Glasses

Abstract: Glasses in the system x M2O ⋅ (1 − x) TeO2 (0 ≤ x ≤ 0.25), where M = Li, Na, K, Rb, Cs, were made by melting in platinum crucibles. Various quenching methods were used to make each glass because some glasses require extremely rapid cooling. Physical properties such as the glass transition onset temperature (Tg) and density (ρ) were measured. In order to explore the short-range structure in these glasses, Raman spectroscopy, infrared spectroscopy, and high-energy x-ray diffraction were used. These experiments on tellurite glasses were performed to find correlations between the physical and structural properties.
