Document Type and Number:
Japanese Patent JPH0650297
Kind Code:
B2
Abstract:
A method of producing an oxygen sensing element including a main body made of an oxygen-ion conductive solid electrolyte, an undulated layer formed on the main body, a measuring electrode formed on the undulated layer for exposure to a measurement gas, and a porous protective coating which covers the measuring electrode. A solid electrolyte material having a higher degree of sinterability than the oxygen-ion conductive solid electrolyte of the main body of the sensing element is prepared, to form an unfired layer for the undulated layer on a selected portion of an unfired body for the main body. The formed unfired layer for the undulated layer is fired together with the unfired body for the main body, under firing conditions selected for the unfired body, whereby the undulated layer is formed as an integral part of the main body of the sensing element.
