Tailoring the Anisotropic Oxygen Transport Properties in Bulk Ceramic Membranes Based on a Ruddlesden-Popper Oxide by Applying Magnetic Fields.

ABSTRACT: Textured Nd₂NiO_{4+ δ} bulk ceramic membranes are fabricated via slip casting in a 0.9 T magnetic field generated by neodymium magnets. This process aligns the oxide grains with their easy-magnetization c-axis parallel to the applied magnetic field. Depending on the magnetic field's direction relative to the slip casting, grains orient either with their a,b-plane or c-axis parallel to the normal direction of the disk-shaped ceramic, thus aligning with the oxygen permeation direction. Without the magnetic field, a non-textured bulk membrane is formed. The microstructure and texture of the ceramic membranes are meticulously analyzed using advanced techniques, including X-ray diffraction, scanning and transmission electron microscopy, as well as related methods.
