Abstract

Dense electrolytes and flawless laminated YSZ electrolytes can be produce combining aqueous tape casting and constrained calendering. During calendering two or more layers are laminated continuously and the edges (entering and final) are not sealed at the same time avoiding air bubbles to trap between the layers. In this study constrained calendering laminates showed adequate adhesion between layers, and almost 20% thickness reduction after sintering as well as high green and sintered densities.
