Abstract
A coating is now disclosed which is especially serviceable as an improved electrocatalytic coating for an electrode. The coating is a crystalline coating of mixed oxides. The oxides are of iridium, ruthenium and titanium, in very specially defined proportions. When the coating is present on an electrically conductive metal substrate that can serve as an electrode, such electrode has, in combination, the characteristics of reduced oxygen evolution in a membrane cell, low chlorine electrode potentials, plus reduced coating weight loss in a caustic environment.
