摘要

The main aim of this study is to investigate the influence of PbO addition on the physical-chemical properties of a SiO_2-Na_2O-CaO-Al_2O_3 matrix of similar composition than the non-volatile fraction of some real wastes. We performed electrical conductivity measurements and MAS NMR at room temperature to characterize the structural modification induced by lead oxide addition. The temperature evolution of the glass structure was investigated by electrical conductivity measurements from temperature above T_g to the liquid state.
