Annotation The analysis of high-porous metal materials (sponges, foams or cellular) with the use of various blowing agents is presented. Two methods of obtaining bulk high-porous nickel carrier catalysts are experimentally investigated: sintering - evaporation process and sintering - dissolution process. The analysis of two technologies for the creation of high-porous materials based on nickel nanopowder obtained by methods of conductor electrical explosion and decomposition of unstable compounds. It is established that the creation of three-dimensional highly porous nickel catalysts with highly developed surface and hierarchical structure of the pore space is possible on the basis of the preliminary pressing of the nanopowders mixtures of metal and blowing agents, followed by sintering metal particles and removal of the blowing agents. At the same time, highly porous material with through porosity of 65-70 % was obtained by sintering-evaporation method using a solid blowing agent; use of nanopowders of nickel with different origin as a feedstock allows us to form a material with a high value of specific surface.
Key words highly porous materials, catalyst carriers, blowing agents, powder metallurgy, nickel nanopowders, pressing, sintering
