Structural, optical, and chemical properties of cadmium phosphate glasses

Abstract

In this study, we prepared cadmium phosphate glasses with various compositions, given by xCdO-(100 - x)P2O5 (x = 10-55 mol%), and analyzed their Fourier transform infrared spectra, dissolution rate, thermal expansion coefficient, glass transition temperature, glass softening temperature, and optical band gap. We found that the thermal expansion coefficient and dissolution rate increased while the glass transition temperature and glass softening temperature decreased with increasing CdO content. These results suggest that CdO acts as a network modifier in binary phosphate glass and weakens its structure.
