Abstract
The best known method for investigating the porous structure of different materials is the method of mercury porosimetry MMP, which has some serious drawbacks. The method of standard contact porosimetry is based on the laws of capillary equilibrium. If two (or more) porous bodies partially filled with a wetting liquid are in capillary equilibrium, the values of the liquid’s capillary pressure p c in these bodies are equal. In this method the amount of a wetting liquid in the test sample is measured and compared with the amount of the same liquid in a standard sample with a known pore structure. Using different working liquids the wetting properties of the test sample can be determined.
