In the present work the effect of copper oxide addition on the densification behavior and electrical conductivity of BaCe 1-x Gd x O 3-Ξ΄ (BCG) type ceramics is investigated. Small addition (1 mol%) of this sintering additive reduces both the calcination temperature (by βΌ250 β’ C) and the sintering te

Preparation, electrical conductivity and stability are discussed for Nd-doped barium cerate with partial substitution of zirconium for cerium. BaCe, ,\_,Zr,Nd, ,O, 95 with 0.1 Ix 5 0.9 was prepared by direct reaction of mixtures of barium carbonate and the corresponding metal oxides. Structural prop
The influence of A:B cation non-stoichiometry on the structural and electrical properties of BaCeO and of 15% Gd-doped 3 BaCeO has been investigated. X-ray powder diffraction and water uptake measurements suggest the occupation of Ba sites 3 by Gd in barium-deficient, doped materials. This phenomeno
