Abstract EN
The polycrystalline ceramic samples of lead barium niobate with general formula Pb1-xBaxNb2O6 (x=0.0 and 0.4) were prepared by conventional solid state reaction method.
The room temperature X-ray diffraction patterns reveal that both of the samples have orthorhombic crystal structure with space group Cm2m.
The dielectric constant and dissipation factor were measured as a function of frequency (100 Hz-2 MHz) and temperature (RT-660K).
The DC electrical conductivity of both the samples was measured from RT to 660 K.
The activation energies calculated from log σ versus 1000/T curves in ferroelectric phase of the compounds are 1.09 eV for pure (x=0.0) sample and 1.36 eV for Ba-substituted (x=0.4) sample.
The values of activation energies show that the substitution of Ba2+ ion on Pb2+ ion site increases the resistivity of pure PbNb2O6 (x=0.0) ceramic.
The modulated differential scanning calorimetry (MDSC) has been used to investigate the phase transition temperature of both the compounds and also to see the effect of Ba2+ ion substitution on the phase transition temperature, specific heat, and other thermal parameters of the compound.
