A porous membrane comprising aggregate particles of a ceramic bonded to one another with the aid of a binder comprising a plastic. The aspect ratio of the aggregate particle is 2.0 or less, and the content of the aggregate particles in the porous membrane is 60 to 99 % by volume. The porous membrane can be easily prepared at low cost and permits improving the productivity. Further, the porous membrane significantly has features of ceramics in terms of strength and corrosion resistance and permits precise control of the pore diameter which is an important factor of separation membranes and filtration membranes.
L'invention porte sur une membrane poreuse comportant des particules d'agrégats de céramique liées entre elles par un liant plastique. L'allongement des particules est de 2 ou moins et leur contenu en volume est compris entre 60 et 99 %. La membrane poreuse, facile à fabriquer et peu onéreuse, permet d'accroître la productivité. En outre, la membrane, qui présente les qualités de la céramique en termes de solidité et de résistance à la corrosion, permet un réglage précis de la taille des pores, important facteur des membranes de séparation et de filtrage.
