| 摘要 |
The invention relates to electrodes, particularly for glass furnaces and is concerned with means for forming good electrical contact between the electrode body and a source of electrical supply, which avoid the problems with known electrodes. The objective of the invention is met by an electrode comprising an elongate ceramic electrode body, connecting the electrode body to a source of electrical supply, characterized by a transverse hole (2) extending through the body (1) towards one end thereof, a slot (3) extending from the transverse hole and emerging at the said one end of the body, a plug member (5) having a cross-sectional shape corresponding to the shape of the transverse hole (2) and being a close fit therein, and being of the same material as that of the electrode or of a chemically compatible material having closely related expansion characteristics as that of the electrode material, and a wrapping of a sheet (4) of noble metal around the plug member (5), the end (4A, 4B) of the sheet (4) extending through the slot (3) to a clamp at that end of the electrode to connect the sheet to a source of electrical supply.
