Abstract

SE TRATA DE UN METODO DE OBTENCION DE METALES POR ELECTROLISIS A PARTIR DE UNA MEZCLA QUE CONTENGA ESPECIES DEL METAL A OBTENER, UTILIZANDO UN ANODO NO CONSUMIBLE FORMADO POR UN METAL, ALEACION O MATERIAL METALOCERAMICO, Y UNA SUPERFICIE ANODICA OPERATIVA QUE CONSISTE EN UN RECUBRIMIENTO DE OXIFLUORURO DE CERIO PRESERVADO POR EL PROCEDIMIENTO DE MANTENER EN LA MEZCLA UNA CONCENTRACION ADECUADA DE CERIO, Y QUE SE CARACTERIZA POR LA UTILIZACION DE UN ANODO FORMADO POR UNA BARRERA IMPERMEABLE AL OXIGENO Y CONDUCTORA DE LA ELECTRICIDAD FORMADA EN LA SUPERFICIE DEL SUSTRATO METALICO, DE ALEACION O UN MATERIAL METALOCERAMICO. ESTA BARRERA DEBE CONSISTIR EN UNA PELICULA DE OXIDO DE CROMO SOBRE UN SUSTRATO FORMADO POR UNA ALEACION QUE CONTENGA CROMO. PREFERIBLEMENTE LA CAPA IMPERMEABLE DEBE SITUARSE SOBRE UNA CAPA DE OXIDO CERAMICO, CON UN NUCLEO DE OXIDO DE COBRE ESTABILIZADO QUE ACTUA COMO ENLACE PARA EL OXIFLUORURO DE CERIO.
