Abstract

METODO DE FABRICACION DE NUCLEOS MAGNETICOS DE MATERIAL FERROMAGNETICO DE CARACTER OXIDO. CONSISTE EN LA PREPARACION DE UNA FERRITA MAGNETICA BLANDA DE LI-ZN-MN, QUE CONTIENE TRIOXIDO DE BISMUTO Y/O PENTOXIDO DE VANADIO, EN CANTIDADES MAXIMAS DE 0,15 A 0,20%, RESPECTIVAMENTE Y, ENTRE AMBOS COMPRENDIDAS ENTRE 0,005 Y 0,20%. LA PREPARACION SE EFECTUA POR MEZCLA DE LAS CANTIDADES ADECUADAS DE FE2O3, ZNO, LICO3, COCO3, BI2O3 Y V2O5 CON ALCOHOL, EVAPORACION DEL ALCOHOL Y CALENTAMIENTO EN AIRE A 900JC; TRITURACION MEZCLADO CON AGUA, EVAPORACION DE ESTA, COMPRESION PARA FORMAR ANILLOS Y SINTERIZACION EN ATMOSFERA QUE CONTIENE OXIGENO, A UNA TEMPERATURA DE AL MENOS 1.050JC. ESTOS NUCLEOS SE EMPLEAN EN BOBINAS DE INDUCCION, TRANSFORMADORES, TELECOMUNICACION Y ELECTRONICA INDUSTRIAL.
