Abstract

METODO PARA LA FABRICACION DE NUCLEOS MAGNETICOS A BASE DE FERRITA DE MANGANESO Y ZINC QUE CONTIENE TITANIO Y COBALTO. CONSISTE EN SINTERIZAR UNA MEZCLA PRECOCIDA DE LOS CONSTITUYENTES DE APRTIDA QUE FORMAN LA FERRITA, A UNA TEMPERATURA COMPRENDIDA ENTRE 1.200GC Y 1.300GC, EN UNA ATMOSFERA CON UNA PRESION PARCIAL DE OXIGENO DE 3,5 X 10 ELEVADO A -2 A 6,5 X 10 ELEVADO A -2 BARES A 1.200GC Y DE 16 X 10 ELEVADO A -2 A 32 X 10 ELEVADO A -2 BARES A 1.300GC; REALIZANDO EL CONTROL CONTINUO DE LOS PARAMETROS TEMPERATURA-OXIGENO, SEGUN LA ECUACION LOG PO2 = -C1/T + C2, EN LA QUE T ES LA TEMPERATURA ABSOLUTA Y C1 Y C2 SON CONSTANTES, DESDE 850GC, AL CALENTAR, HASTA 900GC, AL ENFRIAR. ESTOS NUCLEOS TIENEN APLICACIONES PARA LA FABRICACION DE DISPOSITIVOS DE DEFLEXION DE RECEPTORES Y MONITORES DE TELEVISION, PARA TRANSFORMADORES Y BOBINAS Y EN FUENTES DE ALIMENTACION DE POTENCIA DE CONMUTACION.
