ABSTRACT:
An apparatus for isostatic compression of pulverulent materials comprises a pressure vessel housing two liquids which by a flexible diaphragm are held out of mutual contact. One liquid flows through a pumping circuit and constitutes a primary pressurization agent the pressure of which is, via the diaphragm, transferred to the other liquid surrounding a basket enclosing a soft walled container for the material to be compacted. According to the invention the basket is deformable so that the diaphragm can be pressed against it without being damaged by reactional forces. The result of the deformation capability of the basket is a reduction of the overall size of the pressure vessel.
