EFFECT OF Gd3+: Ag CODOPING ON
THE GLASSES AND VITROCERAMICS OF THE
(1-x-y)[Bi2O3∙PbO]∙xAg2O∙yGd2O3 SYSTEM
Bismuth lead glasses coped with Gd3+: Ag were prepared by the
conventional melt – quenching method. The structure of these materials was
studied by X-ray diffraction (XRD) and FTIR spectroscopy. FTIR spectroscopy
data show that BiO3, BiO6, PbO3 and PbO4 are the most important structural
units in the studied system. These data also made it possible to obtain essential
information concerning the arrangement of the structural units in the studied
glasses and glass ceramics. XRD diffraction shows the presence of δ Bi2O3 and
PbO1.44 crystalline phases.
