Abstract: PbO-Al2O3-B2O3 glasses containing small concentrations of MnO (ranging from 0 to 1.0 mol%) have been prepared. A number of studies, viz., dielectric properties (constant ′, loss tan, a.c.conductivity σac over a range of frequency and temperature), infrared, optical absorption and ESR spectra and magnetic susceptibility of these glasses have been carried out. The analysis of the results indicates that manganese ions exist mostly in Mn3+ state in these glasses when the concentration of MnO is greater than 0.5 mol% in the glass matrix.
