This paper deals with the evaluation of pore size and pore size distri
bution of inorganic membranes by liquid-liquid displacement porometry.
Carbon and ceramic membranes were tested with a fully automatic porom
eter, and different results were obtained depending on the type of mem
brane. Membranes were also examined with the aid of a scanning electro
n microscope. The results of porosimetric measurements are discussed i
n conjunction with those of microscopic observations.
