Abstract

CON EL PROCEDIMIENTO SE ELABORA UNA MATERIA LIGERAMENTE MAGNETICA QUE CONTENGA HIERRO, CON UNA MAGNETIZACION SATURADA ELEVADA Y UNA ESTRUCTURA GRANULADA ULTRAFINA. SEGUN LA INVENCION, SE MUELE EL GRANO INICIAL DE LA MATERIAL, DADO EL CASO CON UN 0,1 A 10% DE LOS ATOMOS DE UN COMPONENTE ADICIONAL INSOLUBLE EN EL, EN PARTICULAS DE POLVO CON UN TAMAÑO MEDIO ENTRE 5 Y 50 NM Y A CONTINUACION SE EFECTUA UN TRATAMIENTO DE CALOR BAJO 600 C, PREFERIBLEMENTE BAJO 400 C DURANTE UNA HORA COMO MAXIMO.
