Smithwick, III, R W

This report describes a method of analyzing mercury porosimetry data without specifying a particular pore shape. An equation, derived from a pore-size distribution function in generalized form, has been used to linearize the compression-corrected mercury-intrusion data of several samples on a log-log plot. Using log-log plots, volume changes due to sample compaction can be straightforwardly identified and then separated from volume changes due to mercury intrusion into pores. Equations have also been derived for calculating surface areas from the slope and intercept parameters of these log-log plots. These surface areas, which are compression-corrected and conpaction-corrected, have agreed well with BET surface areas. These methods of analysis, which have been developed for mercury-intrusion porosimetry, are also demonstrated for water-intrusion porosimetry using an untreated sample of macroporous polystyrene. 5 figures, 1 table.
