摘要: Zinc bismuth silicate glasses with compositions (, and 40) have been prepared by conventional melt-quench technique the solubility limit of zinc in glass system has estimated using X-ray diffraction technique. Density measured Archimedes' principle; increase ZnO samples, molar volume density are found to decrease. The transition temperature () determined differential scanning calorimetry (DSC) is observed content. Raman FTIR spectra recorded at room analysis shows that all compositions, asymmetric symmetric stretched vibrations Si–O bonds SiO4 tetrahedral units exist decrease Bi2O3, contribution begins dominate which results increased compactness structure.
