Thermal and structural properties of ZnO-Bi2O3-B2O3 glasses doped with NiO

Abstract

Among new low melting glasses, bismuthate glass is deemed to have the most potential. Current studies of these glasses focus on the thermal and structural influence of the additional oxide (NiO). The glass transition temperature, Tg and peak crystallization temperatures( Tp1 and Tp2 ) was studied inall samples using a differential scanning calorimeter. We found that the glass transition temperature and crystallization temperature increases with the increase in the content of NiO. Further, NiO-ZnOBi2O3 - B2O3 glasses were investigated spectroscopic ally with Fourier-Transform Infrared (FTIR) spectrarecorded for glass with different main oxide contents. The formation of B-O-Bi and B-O-Zn/Ni bridging bonds in the glass structure is suggested from FTIR spectra. In the present work, the thermal and structural properties of zinc bismuth borate glasses doped nickel ions have been carried out.
