Abstract
Since the development of the first commercial mercury porosi-meter in 19451, mercury porosimetry has become an important technique for the determination of pore size distributions in porous materials. The basic relationship of mercury porosimetry is the Washburn2 equation (1) which gives the pressure, P, required to
intrude mercury intro cylindrical pores of radius r. The surface tension and contact angle of mercury are given by γ and θ, respectively. A typical high pressure mercury intrusion-extrusion curve is illustrated in Figure I.
