This work demonstrates, for the first time, that a variety of disparate and technologically-relevent thermal, mechanical, and electrochemical oxygen-exchange material properties can all be obtained from in situ, current-collector-free wafer curvature measurements.

Host Cation

Cations’ valence and size influence mass diffusion and oxygen defects in ceria. Mass diffusion is limited by Gd3+ under oxidative conditions, where Ce4+ is the host cation, while it is unleashed under reducing conditions, where Ce3+ and Gd3+ have the same charge and similar size. Solid solutions with enhanced electrochemical properties are formed under controlled thermo-chemical conditions.

ABSTRACTGd-doped ceria (Ce0.80Gd0.20O1.90) obtained by several nanopowder synthesis processes are compared structurally, morphologically and electrochemically. The powders have been sintered into pellets and investigated by ac-impedance measurements. The electrochemical properties of the electrolytes have been correlated to the structural morphology of the sintered pellets. When the intergrain region exhibits an elevated interdiffusion, the observation of the grain boundaries becomes difficult while the electrochemical properties are improved. Acrylamide polymerization and oxalic co-precipitation techniques showed the best properties.
