Abstract
A method of making an inert anode (12′) for use in an electrochemical cell first provides a hollow shaped mold (12) where a metal mandrel (17′) having raised male threads (50) at its top diameter (52) is inserted into the mold (12) and a compressible powder (19, 21) added, then the powder is compressed to form recessed female grooves (70) matching the mandrel threads (50) where the mandrel (17′) is engaged and withdrawn along with the compressed powder inert anode after which the mandrel is rotated to unscrew it from the compressed powder and the compressed powder shape is then placed on a tray (27) and heated to sintering temperature.
