abstract The present work was centered on the studies of oxygen permeability, mixed conductivity, dilatometric behavior, crystal structure and microstructure of Ca2Fe2O5±_ and Ca 2(Fe,M)2O5±_ (M = Co, Mn) solid solutions, and dual-phase Ca2Fe2O5 - Ce 0.9Gd0.1O1.95 composites. The anisotropic oxygen-ion diffusion in calcium ferrite lattice was simulated using molecular dynamics and atomistic modeling techniques. The computer simulations results were analyzed in light of the experimental data on ionic conduction and thermodynamic stability. © 2012 IEEE.
