【 摘 要 】

Magnesium Oxide/Praseodymium Oxide (MgO/Pr6O11) nanocomposite was prepared by sol–gel method. X-ray diffraction analysis confirmed the cubic structure. The morphology was studied using high-resolution scanning electron microscopy picture. The AC/DC conductivity and dielectric properties were investigated in the frequency range of 1–4 KHz and in the temperature range of 303–573 K. The results showed that the dielectric constant and the tangent loss were frequency and temperature dependent. The AC/DC conductivity at different temperatures indicated that the conductivity was thermally activated. The activation energy for AC/DC conductivity was calculated using Arrhenius plot.
