Abstract
A cermet seal for high pressure gas discharge lamps which also serves as an electrode, is made from a metallic component suitable for use as an electrode, and a ceramic component which is a metal oxide, by mixing the ingredients in a powdered form, then molded, prefired and then final-fired in a protective atmosphere by sintering into an electrically conductive, vacuum-dense polycrystalline body.
