    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a sintered compact where a sintered compact having excellent characteristics (such as dimensional precision, mechanical properties and appearance) can be safely, easily and inexpensively produced, and to provide a sintered compact obtained by the method for producing a sintered compact, and having excellent characteristics. SOLUTION: The method for producing a sintered compact comprises: a molded body forming stage where a composition comprising inorganic material powders, and a binder including an aliphatic carbonic ester based resin and a second resin whose thermal decomposition temperature is higher than the melting point of the aliphatic carbonic ester based resin is molded, so as to obtain a molded body; a first degreasing stage where the molded body is exposed to an alkaline gas-containing atmosphere, thus the aliphatic carbonic ester based resin is decomposed away from the molded body, so as to obtain a first degreased body; an intermediate stage where the first degreased body is exposed to a low alkaline gas-containing atmosphere whose alkaline gas concentration is lower than that in the alkaline gas-containing atmosphere, so as to obtain an intermediate degreased body; a second degreasing stage where the intermediate degreased body is heated, so as to obtain a second degreased body; and a sintering stage where the second degreased body is sintered, so as to obtain a sintered compact.

    Abstract: PROBLEM TO BE SOLVED: To provide metallic particles which have a nanometric average diameter, have sufficient electroconductivity, have high stability, and can be suitably used for a catalyst material, an electroconductive paste and an ink material. SOLUTION: The method for producing the metallic nanoparticles includes reacting a solution containing a metal salt of an organic acid and an amine with a reducing agent. The colloid of the particle is prepared by dispersing the obtained particles in an organic solvent. The paste and powder of the particle are also prepared by using the particles obtained through the method. COPYRIGHT: (C)2007,JPO&INPIT
