Abstract:
The product formed by the process of:preparing an aqueous suspension of a crystalline nanoscale ceramic electrolyte material; modifying the aqueous suspension by adding coarse particles of the ceramic electrolyte material and at least one water soluble additive selected from a binder and a surfactant; selecting a substrate from a presintered ceramic electrode form, a partially sintered ceramic electrode form, and an unsintered ceramic electrode form; spraying the modified suspension onto the surface of the substrate such that a continuous coating approximately 10-80 microns thick is formed on the substrate upon drying of the suspension; and heating the coated substrate to form a densified ceramic electrolyte material coating approximately 5-40 microns thick.
