Physical characteristics of PbO−ZrO 2 −SiO 2 :TiO 2 glass ceramics embedded with Pb 2 Ti 2 O 6 cubic pyrochlore crystal phase: Part-I electrical properties

Dielectric Relaxation Dynamics and Polaronic Tunneling Conduction Mechanism of Electrical Conductivity of Fe2O3‐Doped PbO–ZrO2–SiO2 Glass Ceramics

“…Other particulars of methods of preparation of the glasses and glass ceramics, the equipment used, and the methods adopted for the characterization (by SEM, XRD, DSC, OA, and IR) of the samples were reported in our earlier papers. [ 10,13,20 ]…”

“…Recently, we have reported the impact of titanium ions on electrical and piezoelectric characteristics of lead zirconium silicate glass ceramics. [ 10,20 ] Motivated by the results obtained in these studies and the predictions discussed earlier, the current study is devoted to investigate the influence of iron ion perovskite crystal phases on the dielectric characteristics ε′ , tan δ , M , Z , and σ ac in the frequency range 4 Hz–8 MHz and in the temperature region, 310–633 K of PbO–ZrO 2 –SiO 2 glasses ceramicized with different concentrations of Fe 2 O 3 .…”
