Synthesis and electrical properties of Gd2MO5 (M = Zr, Hf)
Source abstract
Abstract
Polycrystalline Gd2ZrO and Gd2HfO5 have been prepared by heat-treating coprecipitated oxide mixtures, and their order-disorder phase transitions have been studied in the range 20–1600°C. The materials have been shown to consist of nanostructured grains with a nanodomain size of ∼40 nm. Their electrical conductivity has been determined by impedance spectroscopy in air between 300 and 1000°C. The 1000°C conductivities of Gd2ZrO5 and Gd2HfO5 are 3.7 × 10−3 and 1.8 × 10−3 S/cm, and the respective effective activation energies are 1.37 and 1.56 eV.
