<p>A novel process for producing a porous metallic body to be used as, for example, a filter, which comprises firing a metal oxide molding in an oxidizing atmosphere to give a gas-permeable, porous and reducible metal oxide sinter and reducing the sinter in a reducing atmosphere at a temperature below the melting points of the metals constituting the metal oxide or alloys between these metals, or alternatively firing a metal oxide molding in a reducing atmosphere, thus forming an open-cellular porous metallic body.</p> |
