<P>PROBLEM TO BE SOLVED: To develop a molding composition for powder sintering which is most appropriate for a powder-sintering process. <P>SOLUTION: In the composition, a powder for sintering is carried on a binder resin wherein a solvent-insoluble resin is compounded with a solvent-soluble resin. By forming a green body using this composition and degreasing it to remove only the solvent-soluble resin component, the remaining solvent-insoluble resin component exerts a shape-retention property and prevents the porous green body from losing its shape even after sufficient degreasing until it reaches the sintering step. Therefore, the handling of the green body is drastically improved. <P>COPYRIGHT: (C)2004,JPO |
