Fabrication, characterization, and hydrogen permeation in [BaCe_x Zr_(0.9-x) Y_0.1 O_(3-[delta])] prepared by solid-state reactive sintering
This dissertation focuses on the fabrication and characterization of BCZY for hydrogen-separation applications. The structural and hydrogen-permeation properties of a series of proton-conducting oxides based on the solid solution of BaZrO3-BaCeO3 as an emerging class of ceramic hydrogen-separation membranes were investigated. Yttrium was used as the specific dopant; the ceria and zirconia contents were varied from 0 [less than or equal to] x [less than or equal to] 0.4 BaCe_x Zr_(0.9-x) Y_0.1 O_(3-[delta]). Materials were prepared by solid-state reactive sintering from both BaCO3 and BaSO4 barium ...
