Abstract:
1. A method for producing a sintered compact, comprising: a forming process for obtaining a compact by forming a composition containing metal powder and an organic binder into a predetermined shape; and a baking process for obtaining a sintered compact by baking the compact by using a baking furnace inside which a jig containing silica is provided, wherein in the baking process, a furnace atmosphere of the baking furnace is set to be an atmosphere of inert gas, a furnace pressure is controlled to be 0.1 kPa or more but 100 kPa or less, and the furnace pressure is increased during a heating-up process of the baking process; the furnace pressure is adjusted in the baking process by taking inert gas into the furnace while exhausting gas inside the furnace, the metal powder is stainless steel powder, and the baking process is performed at a maximum temperature of 1000° C. or more but 1400° C. or less for 0.5 hour or more but 8 hours or less.
