PURPOSE:To facilitate decomposition of water soluble macromolecules so as to obtain a strong sintered base stable over a long period by sintering the base in a reducing gas containing water. CONSTITUTION:A slurry composed of nickel powder, water and water soluble macromolecules is applied to a porous conductive core and is dried and then sintered in a reducing gas containing water. Before the core is put in a sintering furnace, the reducing gas such as an ammonium cracked gas, etc., is passed through water so that a base is sintered in the reducing gas containing water. Generation of undecomposed carbon is thereby prevented over a long time and sintering of the nickel powder is accelerated and strong sintered bases are continuously manufactured at low cost. |
