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.

摘要： The present invention relates to an oxygen concentration detector to be used in a system which can simultaneously dispose of the three harmful elements in automotive emissions, i.e., unburnt hydrocarbons (unburnt HC), carbon monoxide (CO) and nitrogen oxides (NOx) through reaction with catalyst. In said detector an oxygen concentration cell comprises a solid electrolyte of a special ceramic material characterized by oxygen ion-conductivity; and the oxygen concentration of a measured gas can be analyzed by measuring the electromotive force generated through a difference in the oxygen partial pressure between the measured gas and a reference gas.
