Structure of inorganic membranes, namely non-modified ceramic matrix and matrix containing nanoparticles of inorganic ion-exchanger based on hydrated zirconium dioxide, is investigated using methods of standard contact porometry, transmission and scanning electron microscopy as well as potentiometry. The porogrammes are simulated by Lorentzian functions; the stripes are related to this or that structure element; the particle sizes are calculated using homogeneous and heterogeneous globular models. The matrix is shown to be formed mainly by particles of micron size; at the same time, the base of the intraporous ion-exchanger layer is globules of 6 nm. The pores, which are formed by the aggregates of nanosize parti-cles of the ion-exchanger, determine charge selectivity of the composite membranes.
