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.

1. A porous article comprising:an article made from a metal; said metal is taken from the group consisting of steel and steel alloys, stainless steel, copper, brass, bronze, aluminum, aluminum alloys, titanium, chromium, nickel and FeCrALY and alloys thereof; said article having a plurality of substantially spherical shaped voids therein; said voids being substantially uniformly dispersed throughout said article; substantially each of said voids intersecting with at least one adjacent void forming a substantially circular window at each intersection. 2. An article as set forth in claim 1, wherein when said article has theoretical density in the range from 5% to 20%, the breaking strength of the article is up to 12000 psi. 3. An article as set forth in claim 1, wherein said article is substantially free from cracks. 4. An article as set forth in claim 1, wherein the average diameter of said circular windows being in the range of approximately 11 microns to 22 microns. 5. A porous article comprising:an article made from a metal; said metal is taken from the group consisting of steel and steel alloys, stainless steel, copper, brass, bronze, aluminum, aluminum alloys, titanium, chromium, nickel and FeCrALY and alloys thereof; said article having a plurality of substantially spherical shaped voids therein; said voids being substantially uniformly dispersed throughout said article; said voids being interconnected with one another;a substantial number of said voids intersecting with at least one adjacent void;windows formed by said intersections; said windows being substantially in the shape of a circle;the average diameter of said circles being in the range from approximately 11 microns to 22 microns. 6. An article as set forth in claim 5, wherein said article is substantially free from cracks. 7. A porous metal article comprising:a metal article having a plurality of substantially spherical shaped voids therein; said voids being substantially uniformly dispersed throughout said article; said voids being interconnected with one another;when the article has theoretical density in the range from 5% to 20%, the strength of the article is up to 12000 psi; the metal constituents of said article comprise steel and steel alloys, stainless steel, copper, brass, bronze, aluminum, aluminum alloys, titanium, chromium, nickel or FeCrALY or alloys thereof. 8. An article as set forth in claim 7, wherein said article is substantially free from cracks. 9. A porous metal article comprising:a metal article having a plurality of substantially spherical shaped voids therein; said voids being substantially uniformly dispersed throughout said article; said voids being interconnected with one another;a substantial number of said voids intersecting with at least one adjacent void;windows formed by said intersections; said windows being substantially in the shape of a circle;the average diameter of said circles being in the range from approximately 11 microns to 22 microns; the metal constituents of said article comprise steel and steel alloys, stainless steel, copper, brass, bronze, aluminum, aluminum alloys, titanium, chromium, nickel or FeCrALY or alloys thereof. 10. An article as set forth in claim 9, wherein said article is substantially free from cracks.
