Glasses in the system xPbO Á (100Àx)P 2 O 5 (x=25-60 mol%) have been investigated using IR spectroscopy and by means of density and electrical-resistivity measurements. The infrared spectra revealed that for PbOo50 mol% PbO enters the structure as a network modifier forming non-bridging oxygen ions.
