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.
