A method of producing an open, porous structure having an outer surface
defining a shape having a bulk volume and having interconnecting openings
extending throughout said volume and opening through said surface, and
products resulting from the method. The method comprises preparing a
viscous mixture comprising a sinterable powder dispersed in a sol of a
polymer in a primary solvent, replacing the primary solvent with a
secondary liquid in which the polymer is insoluble to produce a gel
comprising an open polymeric network having the sinterable powder
arranged therein, removing the secondary liquid from the gel; removing
the polymer network, and sintering the sinterable powder to form the
open, porous structure. Also disclosed are shaped, porous products
resulting from methods of the invention.
