✦ Synopsis

From an examination of a number of graphites using helium pycnometry, vapor pressure measurements, metallography, and the repeated intrusion and distillation of mercury, it was concluded that the results of mercury porosimetry measurement above some critical pressure range often reflect the effect of the measurement as well as the existing porosity. A method employing small-particle statistical techniques developed by Lewis and Goldman") was applied to porosity measurements and numerical descriptions of the pore size distributions were obtained. Both lognormal and non-functional models were employed and examples are given for a number of graphites. * Work performed under the auspices of the United States Atomic Energy Commission. 1. LEWIS H.
