SUMMARY This paper presents a new method of studying pore space of solids with the help of SEM images. The method in question consists of obtaining true images of the specimen microstructure and its further processing by the Image Analyser. The above‐mentioned image appears as the result of superimposing exactly corresponding SEM images which can be observed on both (conjugate) surfaces of the fractured specimen. Therewith, the dark spots on the total image unambiguously represent pores, whilst bright spots represent grains and particles. The following estimates of the pore space are made by automatic Image Analyser of the total image: the determination of total, open and effective porosity; permeability; distribution pores according to its size; the channel tortuosity.
