Glasses of the (50−x/2)Na2O–xZnO–(50−x/2)P2O5(3≤O/P≤3.49) and (50−x)Na2O–xZnO–50P2O5 (O/P=3) (0≤x≤33mol%) compositions were prepared using the conventional melt quenching technique. The increase of density and glass transition temperature in both series is related to the reticulation of phosphate ch...
