摘要

Preparing a solid compact product of determined volume from a powdery composition, comprises placing an initial volume of the powdery composition in a confined space, compacting the powdery composition to a compaction volume of less than or equal to determined volume, maintaining the composition to the compaction volume until the maintaining force decreases by at least 10%, releasing the volume constraint, and obtaining the solid compact product of determined volume.
