Abstract

Método de fabricación de un imán permanente con un valor de (BH)max superior que 2 3 x 106 Gauss-Oersted preferentemente superior que 2 9 x 10 6 Gauss Oersted caracterizado por el hecho de que las particulas de un polvo magnético permanente en el cual los constituyentes esenciales para las propiedades magnéticas son cristales con una estructura de magnetoplumbita de por lo menos un compuesto MO.6Fe2 en que N designa a uno de los metales Ba Sr o Fb y en que una f'racción atómica no mayor que 0 4 de la cantidad de bario y/o estroncio y/o plomo puede estar reemplazada en los cristales por calcio y en que el estado de división del mencionado polvo está adaptado empíricamente para favorecer los referidos valores de (BH)max son unidas para formar un cuerpo magnéticamente anisotrópico y es calentado a una temperatura entre 1150° c. y 1350° C.
