Abstract
The samples of Bi2Vo,9Cu)_0.1-x)Sn_xO_(5.5-δ)(0(?)x(?)0.75) were prepared by solid-state reaction.Room temperature powder X-ray diffraction (XRD) indicates that the synthesized com- pounds present the tetragonalγ-phase structure.The measurement results show that doped-Sn benefits to the control of microstructure of the sample and favor its mechanic property though it doesn't further improve the electrical conductivity of the system.The oxygen permeation measure- ment result indicates oxygen transport in Bi_2V_(0.9)Cu_(0.1-x)Sn_xO_(5.5-δ) system is controlled mainly by the process of surface oxygen exchange.
