“…According to the literature [5,15] it can be seen that the P-O-Sb bonds are corrosion resistant because of their high polarizing power. The results of FT-IR spectra indicate an increase in intensity of the P-O-Sb linkages and explain the improvement of water durability from Na0 to Na10.…”

The influence of ZnO substitution by 0 -12 wt.% Na 2 O on the properties of ZnO-Sb 2 O 3 -P 2 O 5 -Na 2 O glasses has been investigated. The structure and properties of the glasses with the composition of (13.86-x)ZnO-57.93Sb 2 O 3 -28.21P 2 O 5−x Na 2 O (x = 0 -12 wt.%) were characterized by infrared spectra (IR), X-ray diffraction and differential thermal analysis (DTA). The results of IR indicated an increase in the intensity of symmetric vibrations of P-O-P bond, which was confirmed by the improvement of water durability with the increasing amount of Na 2 O in the range of 0 -10 wt.%. Substitution of 10 wt.% Na 2 O led to the weight loss of the glass to 5.93 mg/cm −2 after immersion in deionized water at 50°C for 24 h. The results of XRD showed that the ability of crystallization decreased, indicating the good thermal stability of the glass. The glass containing 8 wt.% Na 2 O had the best properties in every respect and might be an alternative to lead based glasses for the applications, providing further composition improvement.
