Currently available experimental methods to get micro-pore structure characteristics of the porous materials are mercury intrusion porosimetry (MIP), adsorption, NMR, X-ray diffraction, optical microscopy, scanning electron microscopy (SEM), CT scanning, isothermal adsorption, etc [5,6].
Mercury intrusion porosimetry, which can directly get quantitative pore size distribution data with wide range of pore size, is a efficient method to study the pore size distribution of porous materials [3, 4,7,8,9].
One of important macroscopical parameters to characterize porous materials is porosity or void ratio.
