Abstract

MODIFICACIONES INTRODUCIDAS EN UNA CELDA DE REDUCCION ELECTROLITICA PARA LA PRODUCCION DE UN METAL FUNDIDO POR ELECTROLISIS DE UN ELECTROLITO FUNDIDO, MENOS DENSO QUE EL METAL. CONSISTE EN PREPARAR UNA CUBA CON UNO O MAS ANODOS SUSPENDIDOS Y UN SUELO CATODICO, SOBRE EL CUAL SE DISPONE UNA MONOCAPA DE FORMAS DE MATERIAL CERAMICO, MOJABLE O HUMEDECIBLE POR ALUMINIO FUNDIDO, PERO NO HUMEDECIBLE POR EL ELECTROLITO DE LA CUBA. LA SEPARACION ENTRE FORMAS ADYACENTES Y/O LAS ABERTURAS INDIVIDUALES SE ELIGEN DE MODO QUE LAS FUERZAS SUPERFICIALES INTERFACIALES IMPIDEN LA ENTRADA DE PARTICULAS DE LODO RECUBIERTAS DE ELECTROLITO. LAS FORMAS PUEDEN SER ESFERICAS, CILINDRICAS, TUBULARES, DE FORMA DE PLAQUETA, DE PANELES DE ABEJA, ETC. ESTAS CELDAS TIENEN APLICACIONES PARA LA OBTENCION ELECTROLITICA DE ALUMINIO.
