Glasses with compositions (60-x) TeO2 +30B2O3+10ZnO+xEr2O3 (where x=0, 0.5, 1, 1.5 and 2.0 mol%) were prepared by melt quenching method. The chemical durability of these glasses measured from their weight before and after weathering by water and ammonium hydroxide showed significant improvement with...
