ABSTRACT:
A three-fluid method of non-mercury liquid intrusion porosimetry. The sample to be tested and a quantity of non-wetting intrusion liquid other than mercury are introduced into a sealable, pressurizable chamber, the sample being above the intrusion liquid. The chamber is sealed and evacuated. An intermediate pressurizing liquid, such as mercury, is introduced into the chamber and pressurized by a primary pressurization fluid, such as alcohol or oil, so as to force the intrusion liquid into the pores of the sample. The volume of intermediate pressurization liquid introduced into the chamber is measured as the pressure is increased incrementally, to find the pore distribution of the sample.
