Abstract
A method of manufacturing a ceramic body and a gas sensor is disclosed. The method comprises mixing a ceramic material and an organometallic material with a solvent to form a mixture. The organometallic material comprises both a metallic component and an organic ligand. The mixture is disposed onto a surface, dried, and removed to form the ceramic body. The sensor is made by disposing the ceramic body adjacent to an unfired electrolyte body having an electrode disposed on each side thereof to form a green sensor. The green sensor is co-fired to form the sensor.
