Zusammenfassung:	An apparatus for heating powders or powder compacts for consolidation in a pressure vessel having a chamber. There is a device for directly induction heating the powder or powder compact. Additionally, the apparatus is comprised of a device for compacting a powder or powder compact. The device for directly induction heating the powder essentially provides uniform heating to the powder while the compacting device compacts the powder or powder compact in the chamber of the pressure vessel. A method for consolidation of powders or powder compacts which has the steps of heating directly by induction the powder or powder compact, and applying an isostatic stress to the powder or powder compact.
