Web25 mrt. 2024 · Combined with the analysis in section 3 and the fact that the incremental instruction is very low when the pore size is larger than 6 μm, the increase in pore volume is due primarily to mercury intrusion into the cleats >25 μm wide, cleats ranging in width from 6 to 25 μm, and coal matrix pores ranging in aperture from 100 nm to 6 μm at lower, low, … WebMercury porosimetry is used to measure the porosity of a material by applying controlled pressure to a sample immersed in mercury. External pressure is required for mercury to penetrate into the pores of a material due to high contact angle of mercury. The amount of pressure required to intrude into the pores is inversely proportional to the size of the pores.
