Abstract

LA MORFOLOGIA DEL RECUBRIMIENTO DE UN OXIFLUORURO DE CERIO SOBRE UN SUSTRATO CONDUCTIVO DE MEJORA CON LA ADICION DE TANTALIO, NIOBIO Y/O OTROS METALES PENTAVALENTES, MIENTRAS QUE UN RECUBRIMIENTO DE OXIFLUORURO DE CERIO MUESTRA GRIETAS QUE PUEDEN EXTENDERSE A TRAVES DE TODO EL ESPESOR DEL RECUBRIMIENTO, EXPONIENDO ASI LAS PORCIONES LIMITADAS DEL SUSTRATO A UN ATAQUE CORROSIVO, EL RECUBRIMIENTO CN ADITIVO PENTAVALENTE TIENE UNA ESTRUCTURA SUSTANCIALMENTE IMPERMEABLE. ADEMAS, PARA MEJORAR LA MORFOLOGIA DEL RECUBRIMIENTO SE INCREMENTA LA CONDUCTIVIDAD ELECTRICA. EL OXIFLUORURO DE CERIO CON ADITIVO PENTAVALENTE PUEDE PRODUCIRSE POR ELECTRODEPOSICION O SINTERIZACION. LOS RECUBRIMIENTOS SUSTRATOS, O CUERPOS DE ESTE MATERIAL PUEDEN EMPLEARSE COMO ANODOS NO-CONSUMIBLES EN CELULAS DE EXTRACCION ELECTROLITICA DE ALUMINIO LICUADO, COMO SENSORES QUIMICOS, O PARA PROTECCION FRENTE A CORROSION Y OTRAS APLICACIONES.
