Abstract

PROCEDIMIENTO DE PREPARACION DE LAMINAS DELGADAS DE TITANATO DE PLOMO MODIFICADO. PROCEDIMIENTO DE PREPARACION DE SOLUCIONES PRECURSORAS CON COMPOSICIONES BASADAS EN EL TITANATO DE PLOMO MODIFICADO, UTILIZADAS PARA LA DEPOSICION DE LAMINAS DELGADAS FERROELECTRICAS. PARA LA PREPARACION DE LAS SOLUCIONES, SE PROCEDE A LA SINTESIS DE UN GEL DE PLOMO Y TITANIO, A TROVES DE UNA RUTA SOL-GEL BASADA EN LA UTILIZACION DE ALCOXIDOS DE TITANIO MODIFICADOS Y DE DIOLES COMO DISOLVENTES. ESTE GEL PRESENTA LA PROPIEDAD DE REHIDRATARSE EN EXCESO DE AGUA, AL INCORPORAR AL SISTEMA EL ION MODIFICADOR EN FORMA DE DISOLUCION ACUOSA DE ALGUNA DE SUS SALES. ASI, SE OBTIENEN SOLUCIONES HIDRO-ALCOHOLICAS ESTABLES PRECURSORAS DE TITANATO DE PLOMO MODIFICADO. CON ESTE PROCESADO SE SIMPLIFICA Y FACILITA LA FABRICACION, A PARTIR DE SOLUCIONES, DE LAMINAS DELGADAS FERROELECTRICAS DE TITANATO DE PLOMO MODIFICADO, ASI COMO SU INTEGRACION CON LOS MATERIALES SEMICONDUCTORES UTILIZADOS EN DISPOSITIVOS PARA MICROELECTRONICA.
