(Sm1–xEux)2Zr2O7 (0 ≤ x ≤ 1.0) samples are prepared by solid state reaction method using Sm2O3, Eu2O3, and ZrO2 as starting materials. The phase composition and microstructure of (Sm1–xEux)2Zr2O7 ceramics are investigated by X‐ray diffraction (XRD), scanning electron microscopy, high‐resolution transmission electron microscopy (HRTEM) coupled with selected area electron diffraction and Raman spectroscopy...
(Nd1–xGdx)2(Ce1–xZrx)2O7 (0 ≤ x ≤ 0.5) ceramic powders synthesised by the chemical‐coprecipitation and calcination method were pressureless‐sintered at 1,973 K for 10 h in air. The structure and electrical conductivity of (Nd1–xGdx)2(Ce1–xZrx)2O7 ceramics were investigated by the X‐ray diffraction and impedance spectroscopy measurements. (Nd1–xGdx)2(Ce1–xZrx)2O7 (0 ≤ x ≤ 0.5) ceramics exhibit a single...
Pyrochlore oxides of A2Zr2O7, where A represents trivalent rare‐earth elements, have a high electrical conductivity, which makes them suitable for applications as high‐temperature solid electrolytes. The influence of Gd and Yb cations co‐doping at the Nd site on structure and electrical conductivity of a pyrochlore oxide Nd2Zr2O7 is investigated using X‐ray diffraction and impedance spectra measurements...
