摘要: The high temperature durability 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 incorporating in the finely divided metal or metal-metal oxide mixture powder an antisintering material and a pore-forming material capable of subliming or being decomposed, thereby to generate gas upon sintering. The amounts of the antisintering material and the pore-forming material are from 5 to 70% by weight and from 20 to 80% by weight, respectively, based on the total weight of these additives-incorporated metal or metal-metal oxide mixture. The low temperature operation capability of the oxygen sensing element is improved by further incorporating therein a minor amount of a platinum group metal.
