RESEARCH LABORATORY OF HIGH POROUS MATERIALS

Main directions of research works of the department:

         development of high porous materials with cellular structure (foam metals, foam ceramics), having a wide range of operation characteristics; devices using high porous cellular materials; processes of a barrier spraying on the structure of porous materials (protective, catalytic).

          High porous cellular materials have a unique combination of hydraulic (high permeability) and physical and mechanical properties (small density, high rigidity), that is inaccessible during the production of porous materials by traditional technologies from powders, fibres and nets. In the laboratory developed are high porous materials on the base of metals and different kinds of ceramics, which permit to vary their operating characteristics in a wide range depending of their applications.

         It is necessary to mention the main tested developments as follows:

• filters to purify metal melts, hot industrial gases and aggressive liquids, aerosols;
• carriers and catalysts operating in conditions of a high loading, including ones for catalytic conversion of toxic substances in exhaust gases of internal combustion engine and in the production
• electrodes for electric and chemical processes, including nickel electrodes for storage batteries;
• radiating elements of an ecologically pure radiation gas burner;
• cellular materials for implantation including implants with bioactive coatings;
• equipment for low temperature catalytic reburning of ecologically dangerous volatile organic compounds;
• multifunctional equipment for investigation of thermal and mechanical properties of materials at temperatures up to 1600^oC.

         Advantage of developed high porous ceramic materials is in the fact that practically 100% of pores are open in direction of the filtration, that purification of melts with the temperature up to 1600^oC is possible without preliminary heating of the filter; possible is spraying of coatings with a specific surface up to 300 m²/gr on a surface of the structure of high porous cellular materials, as well as catalytically active components (metals of a platinum group, metal oxides).
