Method for producing an open-pore molded body which is made of a metal, and a molded body produced using said method

A process for producing open-pored molded bodies comprising a metal, wherein an open-pored shaped body comprising metal as a semifinished part is coated on its surfaces with particles of the same metal, of which the semifinished part is formed or

• is coated with particles of a chemical compound of the metal of which the semifinished part is made, which chemical compound can be reduced or thermally or chemically decomposed in a thermal treatment and being formed by particles of the respective metal obtained by chemical reduction or thermal or chemical decomposition;
• and
• the coating is followed by at least one thermal treatment in which the particles are joined via sinter necks or sinter bridges to the surface of the semifinished part and/or adjacent particles so that the specific surface area of the open-pored molded body obtained is increased to at least 30 m2/l and/or by at least a factor of 5 compared to the starting material of the uncoated metallic semifinished part, with
• a metal reducing atmosphere or an atmosphere suitable for the decomposition is maintained in the thermal treatment of a coated open-pored shaped body with particles of a reducible or thermally or chemically decomposable chemical compound of the metal of which the semifinished part is made, at least until the reduction or thermal or chemical decomposition of the chemical compound to form the metal is complete.
