Abstract

PROCEDIMIENTO DE PREPARACION DE UN NUCLEO MAGNETICO DE MATERIAL FERROMAGNETICO DE CARACTER OXIDO.MEDIANTE SINTERIZACION DE UN MATERIAL DE PARTIDA COMPUESTO DE FE2O3, MNCO3, ZNO Y LI2CO3 QUE ES TRITURADO EN UN MOLINO DE BOLAS EN PRESENCIA DE AGUA. LA MEZCLA DE POLVO-AGUA SE MANTIENE A 110JC DURANTE 16 HORAS PARA SECARLA Y LUEGO SE TRITURA Y PRECALCINA A 700JC DURANTE 2 HORAS. DESPUES, SE AN/ADEN BI2O3 Y V2O5, SE VUELVE A MOLER EN PRESENCIA DE AGUA DURANTE 6 HORAS, SE SECA A 110JC DURANTE OTRAS 16 HORAS, SE TRITURA Y GRANULA CON AGLOMERANTE Y SE CONFORMA POR COMPRESION SINTERIZANDOSE ENTRE 1.000º Y 1.300JC.DE APLICACION COMO NUCLEOS MAGNETICOS ANULARES DE DISPOSITIVOS DE DESVIACION PARA RECEPTORES DE TELEVISION Y COMO NUCLEOS DE TRANSFORMADORES Y BOBINAS.
