Sr SmxBi(4−x)Ti(4−y)PryO15(for x = 0, y = 0 and x = 0.1, y = 0, 0.1 and 0.2 and also for x = 0.2, y = 0.1) ceramics were prepared by Sol-gel Pechni method. Single phase of compounds was confirmed by XRD analysis and Lattice parameters were calculated. Microstructure and chemical analysis were performed using SEM and EDS techniques. The effect of addition of Sm3+and Pr3+ions on dielectric and polarization properties of Sr Bi4Ti4O15was studied and shift in transition temperature was observed. The dc conductivity of the samples measured as a function of temperature. [ABSTRACT FROM PUBLISHER] |
