Summary
Open-cellular nonorganic foam materials are made by doubling of
foam-polymeric compound structure and have a complex curly structure consisting
of interdependent cells systems. Open-cellular nonorganic foam materials have
extremum high porosity and permeability, heat resistance, corrosion stability,
catalytic reactivity.
