Electrodes for glass furnaces

摘要

A ceramic electrode comprises an electrode body having at least one longitudinal hole, an elongated hollow connector member of a noble metal having a cross-sectional shape corresponding to that of the hole and being a close fit in the hole, and a plug member having a cross-sectional shape corresponding to that of the connector member, and being a close fit within the connector member, the plug being formed from the same material as the electrode or from a material having the same expansion characteristics as the electrode material.
