Pure TeO2 glass was made by a newly developed intermittent quenching technique. Tg and density values were determined for the pure TeO2 glass. Zinc-tellurite and alumina-tellurite glasses were made by melting in Pt crucibles. Tg increases and density decreases as ZnO or Al2O3 is added to the TeO2 matrix. The tellurite structure of the studied glasses was probed by Raman spectroscopy.
