Effet de PbCl2 sur les propriétés d’un verre phosphaté

Abstract

Phosphate glasses with different compositions of PbCl2 were synthesized, differential thermal analysis was performed in order to determine the characteristic temperatures of these glasses and measurements of different glasses density have been performed. The results show that the addition of PbCl2 leads to a nearly linear decrease of the glass transition temperature Tg. They also show a linear increase of the density as a function of PbCl2 content.
