Structural And Electrical Properties oF $(La0.5−xPrxBa0.5)(Mn0.5Ti0.5)O3$ Perovskite Available to Purchase

A single phase monoclinic new perovskite based titano‐manganite $(La0.5−xPrxBa0.5)(Mn0.5Ti0.5)O3$ has been successfully prepared by ceramic solid‐state technique at sintering temperature of 1300° C. The concentration of Pr (Praseodymium), x, in molar proportion in A site has been varied as $x = 0,$ 0.02 and 0.2. Analysis has been carried out to determine the electrical properties of the synthesized material at frequency ranging from 5 Hz to 1 MHz; and at temperature range between 25° C to 200° C. It is found that Pr addition promoted liquid phase sintering diffusion, porosity and agglomeration formation at 1300° C. Dual relaxation is observed in unsubstituted Pr sample $x = 0$ and high Pr substituted sample $x = 0.2.$ This phenomenon was a combinational contribution from a quasi dc (QDC) or low frequency dispersion (LFD), two cole‐cole relaxational responses and a resistor. While low concentrated Pr substituted sampled $x = 0.02$ shows a combinational contribution from a quasi dc (QDC) or low frequency dispersion (LFD), single cole‐cole relaxational response and a resistor at room temperature. Pr substitution at $x = 0$ (max 12000) and $x = 0.2$ (max 16000) showed high dielectric values compared to low substituted sample $x = 0.02.$ Variation of dielectric loss tangent (tan δ) are observed for all samples at temperature ranged studied.
