Abstract

MEJORAS EN UN PROCEDIMIENTO DE ELECTROLISIS EN EL QUE SE USA UN ANODO QUE SE SUMERGE EN EL ELECTROLITO CONSISTENTE EN UN BAÑO FUNDIDO DE CRIOLITA CON ALUMINA, ALIMENTANDOSE LA CORRIENTE A TRAVES DEL ANODO PARAPRODUCIR UNA OXIDACION ANODICA REALIZADA MEDIANTE EL USO DE UN ANODO CONSTITUIDO POR UN CUERPO AUTOSUSTENTADOR CALCINADO CON UNA POROSIDAD ABIERTA DE MENOS DE 1%. DICHO CUERPO ESTA FORMADO ESENCIALMENTE POR UN MATERIAL DE OXIDO DE CERAMICA CON ESTRUCTURA DE ESPINELA, CONDUCTOR DE ELECTRICIDAD Y DE FORMULA (I), EN DONDE MI ES UNO O MAS METALES DIVALENTES DEL GRUPO NI, CO, MG, MN, CU Y ZN; MII ES PREFERENTEMENTE FE; MIII, NB UN METAL DEL GRUPO TI4, ZR4B, HF4B, AL3B, CO3B, CR3B Y LIB, Y F DE 0 A 0,2. ESTE ANODO ES RESISTENTE A LAS CONDICIONES ENCONTRADAS EN LA ELECTROLISIS DE SAL DERRETIDA Y EN PARTICULAR EN LA PRODUCCION DE ALUMINIO.
