ABSTRACT:
The invention relates to a method for preparing a feedstock for injection moulding or for extrusion, consisting of inorganic powders combined with an organic, particularly polymeric binder. This method is characterized in that the constituent particles of the inorganic powders are subjected to a granulation step, prior to their mixing with the polymeric binder.
