Abstract

UNA COMPOSICION PULVERULENTA DE PARTICULAS DE POLVO A BASE DE HIERRO AL QUE SE ENCUENTRA LIGADO UN MATERIAL POLIMERICO SE PREPARA MEDIANTE LA FORMACION DE UNA MEZCLA SECA DE PARTICULAS A BASE DE HIERRO Y PARTICULAS DEL POLIMERO, HUMEDECIENDO LA MEZCLA CON UN DISOLVENTE PARA EL MATERIAL POLIMERICO, CON POSTERIOR ELIMINACION DEL DISOLVENTE PARA DEJAR LIBRE UNA COMPOSICION PULVERULENTA FLUIBLE. LAS COMPOSICIONES DE POLVO PUEDEN SER MOLDEADAS MEDIANTE COMPRESION, GENERALMENTE A TEMPERATURAS POR DEBAJO DE LA TEMPERATURA DE TRANSICION VITRIOSA DEL POLIMERO, PARA LA FORMACION DE COMPONENTES DE NUCLEO MAGNETICO.
