dc.description.abstract | The present work aims at the investigation of the influence of different dopants' ionic radius and concentration on the lattice parameters and the density of Ce(1-x)Ln(x)O(2-delta) (x = 0-0.20; Ln = La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Yb) solid solutions. Moreover, the temperature dependence of the linear expansion of Ce(0.8)Ln(0.2)O(2-delta) ceramics is examined in the range of 300-1173 K and the respective thermal expansion coefficients are calculated. Finally, the total electrical conductivity of Ce(1-x)Ln(x)O(2-delta) (x = 0.15-0.20) and multi-component of Ce((1-x))Ln(x/2)Ln'O-x/2(2-delta) (x = 0.20; Ln = Sm, La, Gd, Dy and Ln' = Dy, Nd, Er, Y) systems is studied in a wide range of temperatures in air atmosphere, as well as in a wide range of oxygen partial pressures at 1023 K and 1173 K. According to the experimental results of the present work, at the highest examined temperature of 1173 K and in air atmosphere, the maximum values of total electrical conductivity are observed in the cases of Ce0.8Nd0.2O2-delta and Ce0.8Sm0.2O2-delta.
