A new technology of porous material production from silver powders is offered.Technology
combining the principles of colloid chemistry and powder metallurgy allows us to synthesize
nanopowders of silver with the particles of mainly platelet shape and small areas of confluence
of round shape particles.The method involves synthesis of precursors on the basis of silver
with the use of organic compounds and their low temperature(175 ◦С) postreduction in a
hydrogen-nitrogen atmosphere. Compacting methods with a pore forming element(food sugar)
and follow-up sintering allowed us to get open porous structure of silver with the maximum
porosity value up to 73 %. The study found that slip casting technology with the use of
paraffin as a connecting element provides production of a homogeneous porous structure of
the material.
