Abstract

See full text

A method is provided for making a porous inorganic membrane by using a mixture of an inorganic material, organic polymer particles and a solvent to form a slurry, the particles being non-spherical, distributing the slurry onto a surface, drying the slurry to remove the solvent and firing the dried slurry to produce the porous inorganic membrane. Examples of organic polymer particles include particles of acrylic. A substrate with a porous inorganic membrane disposed on the substrate is also provided, the inorganic membrane having an average thickness of from about 0.5 micron to about 30 microns, a porosity of from about 30% to about 65%, a median pore size (d50) of from about 0.01 micron to about 1 micron, and a value of (d90−d10)/d50 less than about 2, as measured by mercury porosimetry. An example of a substrate includes an inorganic porous support.
