ABSTRACT:
The invention provides a method and apparatus for making an electrochemical cell solid electrolyte holder. A layer of solid electrolyte powder or its precursor is formed around an externally screw threaded mandrel. The powder is pressed to form the holder in a green state with internal threads formed by the mandrel. The mandrel is screwed axially out of the green holder, after which the green holder is sintered. In the apparatus there is a mandrel which has external threads, and a flexible sheath. The mandrel is receivable in the sheath to provide an annular space around the mandrel for receiving a powder to be isostatically pressed by the sheath. The space is provided between the sheath and a mold, but can, instead, be provided between the mandrel and sheath, or between two sheaths between the mold and mandrel.
