Abstract
Ánodo para el desprendimiento de oxígeno en electrolitos que contienen fluoruros o aniones fluoruro-complejos, incluso en altas concentraciones. El ánodo comprende un sustrato de titanio provisto de una intercapa protectora resistente a la acción agresiva de los fluoruros, y un revestimiento electrocatalítico para el desprendimiento de oxígeno. La intercapa protectora está hecha de tungsteno, óxidos u oxifluoruros, opcionalmente conteniendo metales del grupo del platino en cantidades menores, compuestos metalocerámicos y compuestos intermetálicos, bien per se o bien como óxidos mixtos.
