The method of mercury porometry is widely used to determine the geometric structure of solid porous bodies. The porous structure of granular materials with a granule size of at least 1–2 mm is usually determined. However, in a number of fields (flotation beneficiation processes, powder metallurgy), the objects of study are powders in which the minimum particle size decreases to several tens of microns. The method of mercury porometry is of interest for studying the structure of powders. ...
