FIXED ELECTROLYTIC CERAMICS FOR ELECTROCHEMICAL APPLICATIONS, ESPECIALLY FOR GAS SENSORS, AND METHOD FOR THEIR PRODUCTION

摘要

The proposal is for a solid ceramic electrolyte for electrochemical purposes in which at least two standard commercial ceramic powders with different stabiliser oxide components are used. According to the invention, this provides a solid ceramic electrolyte in a simple production process which unites the advantageous properties of the ceramic powders used, especially the great mechanical strength and resistance to temperature fluctuations of partially stabilised zirconium dioxide ceramic with the good ion conductivity of fully stabilised cubic zirconium dioxide ceramic. The use of the solid ceramic electrolyte of the invention in gas sensors ensures a lower and more durable transition resistance between the solid electrolyte and the electrode.
