Abstract
The NdCrO3 Perovskite Ceramic Compound has prepared by Sol-gel auto-combustion technique. The X-ray diffraction analysis confirmed that single-phase orthorhombic structure. The average size of the grain has estimated and it has found to be ∼50nm. The impedance and permittivity investigations of NdCrO3 Perovskite Ceramic Nanoparticles have performed in the frequency range 20Hz-1MHz and temperature range 150-300K. Impedance spectroscopy studies indicate the presence of grain and grain boundary relaxations in the compound. The polarization mechanism is suggests for change in the dielectric constant and loss with temperature. The Impedance analysis supports the typical behavior NTCR of material. The temperature dependent relaxation time for both grain and grain boundary follows the Arrhenius law.
