Abstract
An improved active electrode for use in planar sensors has been discovered, the electrode prepared by a process comprising combining a base component with a metal paste and heating the paste in the presence of air for a time sufficient to oxidize a portion of the electrode to produce the metal/metal oxide electrode. The electrodes may be incorporated into various planar sensor formats, particularly pH and CO.sub.2 sensors.
Claims9
A method for preparing a planar active metal/metal oxide electrode, said method comprising combining a base component consisting essentially of a salt with a metal paste to form a metal paste mixture, heating the metal paste mixture in the presence of air for a time sufficient to cause said heat to oxidize a portion of the mixture to form said metal/metal oxide electrode.
