Reitveld refinement of the room temperature powder X-ray diffraction profile of NdCrO{sub 3} (NCO) nanoceramics synthesized by sol-gel processing shows orthorhombic Pnma (D{sub 2h}{sup 16}) space group symmetry. The refined lattice parameters are a = 5.482(3) A, b = 7.689(4) A and c = 5.416(3) A. Transmission electron microscopy (TEM) of NCO shows that the average particle size is around 70 nm. The electrical transport property of NCO is investigated by both conductivity and electric modulus formalism. The electrical data is taken by a LCR meter in a temperature range from 303 K to 573 K and in a frequency range from 42 Hz to 1.1 MHz. The ac conductivity follows a power law. The Cole-Cole plot of impedance at 303 K shows grain effect.
