Abstract: Designed composition of ceramic mass for synthesis of the high-alumina ceramic substrates for production multilayer microfiltration membranes. Electrocorundum (fraction 100–250 microns) was used as filler for producing of the high-alumina substrates, as a binder – kaolinite-hydromica clay and aluminoborosilicate glass and chalk. Formation of material carried by dry pressing at the pressure of 60 MPa, the temperature of synthesis was 1200–1300 °C. The effect of the sintering temperature of the material, the amount and composition of binder on the porosity, mechanical strength, permeability and porous structure of high-alumina permeable porous substrate was investigated. The structure of the substrate is represented by an extensive network of slit-shape pore channels, an average equivalent pore diameter – 10–40 μm. The material has the following set of physicochemical properties: mechanical compressive strength is 27.41 MPa, open porosity – 36.49%, permeability coefficient – 2.07·10-7 m2. The possibility of application of permeable high-alumina porous substrates as macro- and microfiltration elements in the dairy industry was researched. Designed multilayer high-alumina ceramic materials for disperse systems microfiltration with active layer received in Al2O3-CuO, Al2O3-TiO2-MnO2 systems. The average pore diameter of the microfiltration layers is 1–10 μm, 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.
