Abstract

Procédé de production de membrane dotée d'une pluralité de pores de taille de l'ordre de l'angström, selon lequel une poudre comportant des particules de taille de l'ordre du nanomètre est comprimée pour former une membrane poreuse constituée de poudre consolidée. Dans un mode préféré de réalisation de la présente invention, la poudre est comprimée par compression isostatique à froid.
