Abstract
The present invention is an improved yttria-stabilized zirconia electrode having a ceramic tube ( ). The electrode is improved by replacing the method of sealing the electrode with an epoxy seal ( ) and filling the tube with a ceramic glue ( ) without completely filling the tube. The ceramic glue is added in a small amount and the ceramic glue is heated in the tube before a next small amount of ceramic glue is added, until the final amount of ceramic glue is added and heated. Also, an area of cover on a wire ( ) in an area between a top of the ceramic glue and a top of the tube is partially removed. A sealing glue above the top of the ceramic glue that adheres to the wire at the removed area of the cover, adheres to the tube and seals the top of the tube. Finally, an outside portion of the wire which extends beyond the top of the tube is gripped with a CONAX fitting ( ), instead of the fitting gripping the tube.
