Abstract
This specification discloses a method and apparatus for forming and extruding ceramic materials. The apparatus utilizes a vacuum chamber mounted within a heating chamber or element; and the ceramic forming chamber is mounted within the vacuum chamber. A press is slidably mounted within vacuum and forming chambers in order to apply pressure to the ceramic materials during the heating step and subsequently during the ceramics extrusion step. The heating chamber applies heat to the vacuum chamber and forming chamber during the sintering and extrusion step. The forming chamber preferably remains in position within the vacuum chamber during the entire ceramic article manufacturing process.
