This study investigates the application of robocasting technology for fabricating high-density yttria-stabilized zirconia (8YSZ) electrolytes used in solid oxide fuel cells (SOFCs). The primary goal is to overcome the limitations of traditional manufacturing techniques, such as low density and poor microstructural control. Using a combination of hydrothermal synthesis, rheological testing, and robocasting, we achieved dense 8YSZ structures (over 95% density) with minimal porosity. The fabricated electrolytes underwent sintering and debinding processes, with thermal treatment profiles optimized for structural integrity. A microstructural analysis through SEM and XRD confirmed the formation of stable crystalline phase. This research opens new avenues for the…

Single-crystal microstructure can bring high performance for many materials including piezoelectrics, semiconductors, and cuprate superconductors. Unlike single-crystal metals that can be machined into complex components, most single-crystal ceramics are limited to the shape of thin films or plates due to their brittleness. However, more designs of advanced devices need to break these geometric limitations. 3D-ink-printing can efficiently fabricate complex architectured ceramics, but the microstructure is polycrystals. Here, for the first time, we demonstrate a route to grow single-crystal on 3D printed ceramic-YBa2 Cu 3 O7-x (YBCO) superconductors that can simultaneously have complex architectures and high critical current density. An ink…
