Abstract: |

|
Observed temperature dependence of dielectric constant, loss tangent and dielectric conductivity of H- phase [Ta2O5]1-x-[TiO2]x, (0.078 ≤ x ≤ 0.085) pellets, prepared by solid state reaction method, has been presented. Dielectric constant was observed slowly increasing with temperature showing strong transition peaks at 495, 505, 510 and 520 oC for the compositions with x = 0.078, 0.080, 0.082 and 0.085, respectively. Dielectric loss and conductivity also show anomalous increase near the transition temperature, for all the prepared compositions. Near the transition temperature, anomalous dielectric behavior may be associated with the softening of the active phonon mode. |
