Description
Summary:The principle and technique of porometry, the measurable pore structure characteristics, and the significance of the measured quantities are reviewed. Advances in porometry and their applications are considered. Recently developed innovative and novel techniques used for porometry are also discussed. The theory of porometry is explained. Procedures for the evaluation of pore throat diameter, pore distribution, surface area, and permeability, and the interpretation of results are considered in detail. Porometers with the capability to measure pore structure under compression, at elevated temperatures, under controlled chemical environment, and under many other special situations are considered. The novel techniques, capillary condensation flow porometry and liquid‐liquid porometry, are also considered.
