Inkjet Printing Towards Dense Spinel Protective Coatings for Solid Oxide Cell (SOC) Applications

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT This study aimed to develop a dense protective coating of Mn1.7Cu1.3O4 spinel on SOC interconnects using inkjet printing. The work focused on formulating a well‐dispersed, stable, and agglomerate‐free ink to obtain a dense, uniform, and full surface coating layer. Achieving a dense layer, requires an ink with high powder content.
