Deformation of perovskite electronic ceramics - a review.

Journal Article · · Solid State Ionics
Steady-state deformation of several important electronic ceramics, all having a perovskite structure, is reviewed and discussed in terms of their common prominent features. Of particular importance are the ferroelectric BaTiO{sub 3}, a leading candidate for electrodes in solid-oxide fuel cells, (La{sub 1-y}Sr{sub y}){sub 1-x}MnO{sub 3-{delta}} and the high-temperature superconductor YBa{sub 2}Cu{sub 3}O{sub x}. In all cases, deformation occurs by grain-boundary sliding accommodated by diffusion. Cations are the rate-controlling species and their diffusivities can be calculated and compared to existing tracer diffusion data. In some cases, the tracer diffusion coefficients have not been measured, but measurements of steady-state creep can provide these values.
