<p>Isostatic compaction appts. for pulverulent material comprises a pressure vessel which contains two liquids separated by a flexible partition. The material is housed in a container which is supported in a deformable container in the vessel. The deformable container is in contact with one liquid which may be pressurised, via the flexible partition, by the other liquid which constitutes the primary pressurisation agent. The partition contacts the deformable container upon pressurisation of the liq. to compact the material and containers. Used in high pressure powder compaction techniques. Provision of a deformable container permits contact with the flexible partition without damaging the latter. The increased deformation capability of the deformable container results in a reduction in the overall size of the pressure vessel with respect to apparatus that utilizes only a single liquid pressurizing medium.</p> |
