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.WITH THE PROCEDURE A SLIGHTLY MAGNETIC MATTER IS MADE THAT CONTAINS IRON, WITH A HIGH SATURATED MAGNETIZATION AND AN ULTRAFINE GRANULATED STRUCTURE. ACCORDING TO THE INVENTION, THE INITIAL GRAIN OF THE MATERIAL IS GRINDED, GIVEN THE CASE WITH 0.1 TO 10% OF THE ATOMES OF AN ADDITIONAL COMPONENT INSOLUBLE IN IT, IN POWDER PARTICLES WITH A MEDIUM SIZE BETWEEN 5 AND 50 NM AND CONTINUATION HEAT TREATMENT IS PERFORMED UNDER 600 C, PREFERABLY UNDER 400 C FOR A MAXIMUM HOUR.
