Stereolithographic Additive Manufacturing of Zirconia Electrodes with Dendritic Patterns for Aluminum Smelting

Zirconia electrodes with dendritic patterns were fabricated by stereolithographic additive manufacturing (STL-AM). A solid electrolyte of yttria-stabilized zirconia (YSZ) was selected for oxygen separation in the molten salt electrolysis aluminum smelting without carbon dioxide excretion. Thereafter, 4, 6, 8 and 12-coordinated structures composed cylindrical lattices designed as computer graphics. The specific surface area each structure maximized changing aspect ratio. spatial profile pressure hot liquid propagation dendrite systematically visualized computational fluid dynamics (CFD). During fabrication process, a photosensitive resin containing particles spread on substrate, an ultraviolet (UV) laser beam scanned to create two-dimensional (2D) cross-section. Through layer laminations, three-dimensional (3D) objects successfully fabricated. ceramics obtained through dewaxing sintering.
