Abstract
Abstract
Highly porous permeable nickel materials with a hierarchical structure were consolidated by powder metallurgy methods in sintering-dissolution and sintering-evaporation processes from nickel nanopowder and micropowders of two different types of space holders – water-soluble sodium chloride NaCl and thermally unstable ammonium bicarbonate NH4HCO3, respectively. Nanopowder nickel materials with three levels of hierarchical porosity were obtained using bidisperse micropowders of soluble NaCl space holder.
