Mixed metal oxide activated titanium anodes consist of an acid insoluble, crystalline, anhydrous, electrically conductive, electrocatalytic coating on a titanium base. This type of anode completely displaced graphite in the chlor alkali industry during the decade of the seventies and is now gaining acceptance in the cathodic protection industry. The low consumption rate of the electrocatalytic coating at recommended operating current densities results in projected anode lives of 15 to 20 years. The workability of titanium allows anodes to be formed in several shapes including tubes, rods, wire, and mesh. Tubular anodes with mechanical seals and mechanical center connections are particularly suitable for ground beds. These anodes can be easily installed in 15 cm (6 inch) diameter holes. Stable currents are reported from an open hole installation of May, 1984, and several deep ground bed installations of October - November, 1985.
