Conclusions
Using as an example a series of refractory materials, it is shown that depending on the moisture content, the type of power, and the liquid used, there is a wet decompaction or compaction by comparison with the original packing density of the powders in a free-pouring state. The moisture-loosening effect may be quite significant (1.5–2.2-fold) and must be taken into account in production processes.
