Abstract
Low temperature operability of an oxygen sensing element, which comprises a solid electrolyte member composed of sintered material, and a means for providing a reference oxygen partial pressure, composed of a sintered product of a finely divided metal or metal-metal oxide mixture powder and being completely embedded within the solid electrolyte member, is improved by the incorporation of from 0.5 to 10% by weight, based on the total weight of the sintered product, of a finely divided platinum group metal powder in the sintered product of the reference oxygen partial pressure-providing means.
