Process for producing metallic or ceramic shaped bodies
A process for producing a metallic or ceramic shaped body from a thermoplastic material comprising A) 40 to 65% inorganic sinterable powder A B) 35 to 60% binder B1) 50 to 95% polyoxymethylene homo- or copolymers; B2) 5 to 50% of a polymer dissolved or dispersed in B1) with a particle size of less than 1 μm, and C) 0 to 5% by volume of a dispersing aid, by injection molding or extrusion to give a green body, removing the binder and sintering, which comprises removing the binder by a) treating the molding with a solvent which extracts the binder component B2) from the molding and in which the binder component B1) is insoluble, b) removing the solvent from the molding by drying, and c) treating the molding in an acid-containing atmosphere is described.
