Mercury intrusion porosimetry (MIP) is an analytical technique used to characterize the pore structure of materials. It involves the forced intrusion of mercury into the pores of a porous material under controlled pressure. Mercury is non-wetting, meaning it does not naturally enter the pores of most materials; therefore, the pressure required to force mercury into the pores is directly related to the size of the pores. This technique provides valuable information about pore size distribution, pore volume, and surface area.
