Document Type and Number:
Japanese Patent JPH0778481
Kind Code:
B2
Abstract:
An oxygen sensing element having an oxygen-ion conductive solid electrolyte body, a measuring and a reference electrode formed on the solid electrolyte body so as to communicate with a measurement and a reference gas, respectively. The solid electrolyte body is formed by firing an unfired body of an oxygen-ion conductive solid electrolyte material containing a sitnering aid. The firing temperature is selected within a range defined by a permissible lowest sintering point of the unfired formed body, and an upper limit which is 60 DEG above the permissible lowest sintering point, whereby an amount of the sintering aid left on the surface of the first solid electrolyte body is smaller than that left within an interior structure of the solid electrolyte body, as viewed in a transverse cross sectional plane of the solid electrolyte body.
