An improved porous article and a method for forming such porous article are provided. A mixture of ceramic or articles and pliable organic hollow spheres is prepared in a liquid typically as a suspension. The article is formed by pressing, slip casting, extruding or injection molding the mixture. The article is dried to remove the liquid, and then is fired so that the particles are bonded such as by sintering, and the organic spheres are eliminated, resulting in a strong porous article having uniformly spaced interconnected voids.
