Abstract
In this work, nanostructured (La0.6Sr0.4)0.99CoO3 (LSC)-Ce0.8Gd0.2O1.9
(CGO) core-shell particles were prepared by precipitating CGO
nanoparticles on the surface of LSC particles under hydrothermal
conditions. The as-prepared core-shell particles were sintered by spark
plasma sintering (SPS) and conventional sintering, and the
microstructure evolution and densification behavior were studied. Dense
microstructures were reached using both sintering methods at relatively
low temperatures. In the case of SPS, the core-shell architecture was
partially maintained and nano-structured CGO grains were formed, while
conventional sintering led to the formation of larger CGO grains. This
work covers a detailed characterization of (a) the individual LSC-CGO
core-shell particles and (b) the composites after densification.
