摘要：
A clayish composition for producing a molded article of noble metal consists essentially of a noble metal powder, starch and a water-soluble cellulose resin as organic binder and water. The contents of the starch and the water-soluble cellulose resin each fall in the range of 0.02-3.0% by weight, based on the total amount of the organic binder and the noble metal powder. A method for producing the sintered article of noble metal consists essentially of a step for producing the clayish composition mentioned above, a step of molding the clayish composition in a desired shape, a step of drying the molded article and a step of sintering the dried molded article.
