摘要：

Electrical properties of the high oxide ionic conductive ceramic RE10Si6O27 (RE = La, Pr, Nd, Sm, Gd, Dy) sintered at 1700-1800 degrees C by the use of MgO-stabilized zirconia setter during a sintering have been investigated The lowest activation energy and the highest conductivity at 200 degrees C were achieved for Pr10Si6O27 (55.4 kJ mol(-1)) and La10Si6O27 (1.32x10(-5) S cm(-1)), respectively. The conductivity of La10Si6O27 at 200 degrees C was higher by order of 1.5x10(1) times than that (8.82x10(-7) S cm(-1) at 200 degrees C) of (Bi2O3)(0.75)(Y2O3)(0.25). The three-point bending strength of La10Si6O27 was 100 MPa. (C) 1998 Elsevier Science Limited. All rights reserved.
