Abstract

Bei einem Verfahren zum Herstellen von Formteilen aus Metall­ teilchen wird durch ein Formpressen und einem anschließenden Sintern in die Poren des Sinterteiles pulverförmiges Schicht­ silikat und ggf. Graphitpulver eingepreßt. Als Schichtsili­ kat kann Glimmer verwendet werden. In a process for producing molded parts from metal Particle is obtained by compression molding and a subsequent one Sintering in the pores of the sintered powdery layer silicate and possibly graphite powder pressed. As a layer sili kat can be used mica.
