Abstract
The invention discloses a new electrode suitable for use as an anode for oxygen evolution from electrolytes containing fluorides or fluoride-complex anions even in high concentrations. The anode of the invention comprises a titanium substrate provided with a protective interlayer resistant to the aggressive action of fluorides, and an electrocatalytic coating for oxygen evolution. The protective interlayer is made of tungsten, oxides or oxyfluorides, optionally containing metals of the platinum group in minor quantities, metallo-ceramic compounds and intermetallic compounds either per se or as mixed oxides.
