Method of manufacturing a reference electrode

Abstract

A method of manufacturing a reference electrode which has a shaft into which a diaphragm body of a porous ceramic is incorporated is comprised of the following method steps: Impregnating the ceramic with a lyogel precursor prior to incorporating the ceramic body into the shaft, and subsequently transforming the lyogel precursor into a lyogel, from which the solvent is removed through a drying process. A reference electrode has a shaft that is filled with electrolyte, and a diaphragm body formed of a porous ceramic and containing a system of hollow spaces is incorporated into the wall of the shaft. The system of hollow spaces is filled at least partially with a material that is formed of a lyogel by drying and has at least one component that corresponds to the ceramic material.
