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 Lorentz functions, the stripes are related to corresponding structure element, and the particle size is calculated, using homogeneous and heterogeneous models. As shown, the matrix is 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 aggregates of nanosize particles of the ion-exchanger, determine charge selectivity of the composite membranes.
