N2 - Basic stages of porous cermets preparation from MeAl (Me = Cr, Cu, Co, Fe) powders are elaborated including mechanical activation of Me-Al blends, soft hydrothermal treatment of mechanically alloyed blends followed by thermal treatment thus allowing to control their mechanical, thermophysical and textural properties. Ceramometal monoliths with metallic particles (up to 80 wt.%) randomly distributed in the oxide matrix are characterized by the hierarchical pore structure with developed ultramacropores which provides their high permeability. Mesoporosity of ceramometal monoliths was developed by incorporation of mesoporous components into their structure. Monolithic catalysts based on these cermet substrates were shown to be promising for different fields of application in catalysis.
