<p>A novel valve metal electrode for use in an electrochemical process at an anodic current density of up to about 215 milliamps per square meter which is particularly suited for use as an anode in the cathodic protection of iron or steel bars embedded as reinforcing elements in a concrete article. The useful lifetime of the electrode at any given anodic current density can be extended by appropriate heat treatment prior to use.</p> |
