Electrophoretic deposition of solid electrolytes for non-nernstian electrochemical gas sensors

The study of electrophoretic deposition (EPD) of CeO₂ powder as a solid electrolyte for mixed-potential gas sensors will be presented in this paper. Cerium (IV) dioxide was deposited from colloidal suspensions. The grow process of layers and the influence of the process conditions on the sensing layers parameters will be described. The solid electrolyte layers obtained with this method, reveal good repeatability and adhesion. The achieved results suggest that EPD process is a promising method for the solid electrolyte deposition.
