Abstract

PARTICULAS ATRAIBLES MAGNETICAMENTE CONTIENEN UN NUCLEO DE MATERIAL MAGNETICO ENCAPSULADO EN UN RECUBRIMIENTO DE OXIDO METALICO. SE PUEDEN FABRICAR EMULSIONANDO UNA DISLOUCION O DISPERSION ACUOSA DE MATERIAL MAGNETICO O PRECURSOR, Y UNA DISOLUCION ACUOSA O SOL DE UN OXIDO INORGANICO DE RECUBRIMIENTO PRECURSOR, EN UN LIQUIDO INERTE INMISCIBLE EN AGUA. LAS GOTITAS ACUOSAS SE GELIFICAN, POR EJEMPLO, MEDIANTE AMONIACO O UNA AMINA, RECUBREN Y CALIENTAN A 250-2000 (GRADOS) C. LAS PARTICULAS RESULTANTES GENERALMENTE SON ESFERAS LISAS DE DIAMETRO INFERIOR A 100 (MU) Y CON FRECUENCIA DE TAMAÑO SUB-MICRO.
