MOLDING COMPOSITION FOR POWDER SINTERING, METHOD OF SINTERING POWDER FOR SINTERING, AND SINTER MEMBER MADE FROM THE POWDER

摘要

A composition characterized by comprising: a binder resin comprising a solvent-soluble resin and a solvent-insoluble resin incorporated therein; and a powder for sintering which has been fixed to the binder resin. When this composition is used to form a green molding and the solvent-soluble resin ingredient only is removed from the green molding, then the solvent-insoluble resin ingredient remains to maintain the shape of the green molding. Although this green molding is porous, it is prevented from deforming over the period of from the sufficient degreasing to a sintering step. The degreased green molding is hence significantly easy to handle, and the sinter which is being produced does not deform during sintering.
