Synthesis and structural studies of Na2O-ZnO-ZnF2-B2O3 oxyfluoride glasses

This paper describes the synthesis and spectroscopic studies of the glass system, 20Na 2 O-(20- x ) ZnO- x ZnF 2 -60B 2 O 3 ( x = 0, 5, 10, 15, 20), prepared by melt quenching method. The analyses of DSC and XRD did not show the crystallinity of the glass sample. 11 B MAS-NMR shows the presence of s...

Zusammenfassung:This paper describes the synthesis and spectroscopic studies of the glass system, 20Na 2 O-(20- x ) ZnO- x ZnF 2 -60B 2 O 3 ( x = 0, 5, 10, 15, 20), prepared by melt quenching method. The analyses of DSC and XRD did not show the crystallinity of the glass sample. 11 B MAS-NMR shows the presence of sharp peak around −14 ppm. From the IR studies, the broadening of the peak around 1200–1400 and 800–1100 cm −1 shows the presence of mixed linkages like B-O-B, B-O-Zn in the network.
