The dielectric constant and dissipation factor were determined as function of temperature in the range (RT-160 oC) at fixed frequencies of (0.1,1,10) KHz for Pure BaTiO3 sintered at (1400 oC ) and (Mn+3–doped BaTiO3) sintered at (1350, 1400 and 1450 oC) for four hours. The activation energies were calculated from the (Arrhenius-Plot) for a pure and doped samples sintered at the same temperature at 10 KHz. Phase identification of the pure and Mn-doped samples in ceramic form were determined by (XRD) using the standard “JCPDS files”.
