Structure, Microstructure and Transport-Properties of Mixed Ionic-Electronic Conductors Based on Bismuth Oxide .1. Bi-Y-Cu-O System
An ionic-electronic mixed conductor consisting of a stabilized fcc Bi1.5Y0.5O3 ionic conductive matrix phase, and a tetragonal Bi-2 Cu-1-n(2+) Cun1+O4-0.5n, electronic conductive second phase has been developed. The ionic transference number and conductivity of the composite material depend critically on the amount of the bismuth copper oxide second phase and its morphology.
