Effects of temperature and Nd composition on non-linear transport properties in substituted Ce1−xNdxO2−δ cerium dioxides

From cerium oxycarbonate to nanostructured ceria: Relations between synthesis, thermal process and morphologies

“…Nanostructured powders of pure and doped ceria can be obtained in various ways. Usually, nanoparticles can be prepared using a ''sol-gel'' process [18][19][20]. However, other types of processes exist, such as solid-state reaction at ambient temperature [21], thermal decomposition [22,23], micro-emulsion synthesis [24], co-precipitation [25,26] and hydrothermal synthesis [27].…”

Grain boundary conductivity of high purity neodymium-doped ceria nanosystem with and without the doping of molybdenum oxide

“…The deleterious GB behavior arising from SiO 2 impurity has been recognized in zirconia-based electrolytes for several decades and in ceria-based ceramics for over 10 years. And recently, the grain boundary performance of the transition oxide-doped GDC high pure or impure systems has been systematically investigated [16][17][18][19][20][21][22][23], while much less information is available about Nd 2 O 3 -doped CeO 2 (NDC) system mentioning the SiO 2 content, although some literature data are available regarding the ionic conductivities as a function of dopant contents [24][25][26]. It is, therefore, necessary to prepare high purity NDC solid solutions and investigate the electrical conductivity of this system.…”

Influence of the sintering temperature on electrical property of the Ce0.8Sm0.1Y0.1O1.9 electrolyte

“…These materials demonstrate much higher ionic conductivity at relatively lower temperatures in comparison to that of the traditional electrolyte yttria-stabilized zirconia (YSZ). So far, many studies have been carried out on doped ceria and made much progress [3][4][5][6][7][8][9][10][11]. Some singly doped electrolytes, such as Ce 1−x Sm x O 2−y , Ce 1−x Gd x O 2−y , Ce 1−x Y x O 2−y , etc., show high oxide ion conductivity.…”
