The processes of structure formation of permeable high-alumina ceramics for microfiltration of disperse hydrosystems were investigated. Structure of the meterials received in Al2O3-CaO system is represented by Cu Al O2 crystals agglomerates, which allows obtaining a microfiltration material with an extensive network of slit-shape pore channels. The structure-forming particles of membrane received in Al2O3-TiO2-MnO2 are represented by macroporous particles which give unique filtering properties for the material due to adsorption and electrosurface interactions. The average pore diameter of the microfiltration materials received at 1250 C is 1-10 vm, the open porosity - 38,90-48,42 % , the permeability coefficient of the multilayer membranes (thickness 6,15-6,25 mm)-(1,566-1,669) 10-7 m2.
