A large glass-forming domain has been identified in the Pb2P2O7-Ag4P2O7-AgI
system. The physical properties have been determined as a function of AgI
content. The ionic conductivity has been studied as a function of the Ag+ i
on total concentration and the Ag+ ion concentration issued from the AgI co
mponent. The structure and electrical properties of obtained glasses are co
mpared with those of ionic glasses of the Ag4P2O7-AgI system. (C) 2001 Else
