Abstract
A cathodic protection electrode is mounted in an iron bushing by way of a ring of alumina or forsterite, the bushing being mounted in a glass-lined metallic vessel, such as a water heater. The electrode comprises a solid solution of MFe.sub.2 O.sub.4 (wherein M is at least one metal selected from the group consisting of Mn, Ni, Co, Mg, Cu and Zn) of 0.15 to 87.1 mol%, and Fe.sub.3 O.sub.4 of 99.85 to 12.9 mol%.
