Abstract

A new structural model for the interpretation of Hg porosimetry data for samples having a bimodal pore size distribution is presented. The morphol. of the macropore network of a porous solid was studied using a combination of Hg porosimetry and NMR techniques. The model consists of a lattice-based network of pore bodies and pore necks. The model enables assessment of the spatial geometric distribution of the directly accessible macropore network of a porous material having a bimodal pore size distribution. A methodol. that can be used to det. the spatial distribution of the crit. pore neck diams. controlling access to the macroporous void space also was described. This method was used to provide a map of the local crit. macropore neck distribution over macroscopic length scales for an alumina tablet that is not possible with other techniques.
