Two distinct glass-forming regions were found in the 50ZnO-xBi2O3-(50−x)P2O5 glass series with x=0-10 and 20-35mol.% Bi2O3. All prepared Bi2O3-containing glasses reveal a high chemical durability. Small additions of Bi2O3 (∼5mol.%) improve thermal stability of glasses. All glasses crystallize on heating within the temperature range of 505-583°C. Structural studies by Raman and 31P MAS NMR spectroscopies showed the rapid depolymerisation of phosphate chains within the first region with x=0-15 and the presence of isolated Q0 phosphate units within the second region with x=20-35. Raman studies showed that bismuth is incorporated in the glass structure in BiO6 units and their vibrational bands were observed within the spectral region of 350-700cm−1. The evolution of properties and the spectroscopic data are both in accordance with a network former effect of Bi2O3.
