Glass transition (Tg) and dielectric loss in Na3PO4-Pb3(PO4)2-BiPO4 phosphate glasses

Thermal and dielectric loss properties of Na 3 PO 4 -Pb 3 (PO 4 BiPO 4 (Na 2 O-PbO-Bi 2 O 3 -P 2 O 5 ) phosphate glasses, have been studied by the differential scanning calorimetry (DSC) and electrical factor loss (tgδ) measurements. Experiments have been carried out from ambient temperature to 500°...

Description
Summary:Thermal and dielectric loss properties of Na 3 PO 4 -Pb 3 (PO 4 BiPO 4 (Na 2 O-PbO-Bi 2 O 3 -P 2 O 5 ) phosphate glasses, have been studied by the differential scanning calorimetry (DSC) and electrical factor loss (tgδ) measurements. Experiments have been carried out from ambient temperature to 500°C and show a strong influence of sodium ions on T g and tgδ.
