Vitreous carbon foams were manufactured by two routes. The first one comprised the impregnation of the sacrificial template made from spherical carbamide particles with the epoxy precursor resin. Another one comprised multiple impregnation of the polyurethane foam template with the phenolic resin. The samples were subjected to pyrolysis with the highest heat treatment temperatures within 700-2000oC. Both approaches ensured cellular vitreous carbons with the interconnected open porosity and the controllable density within 0.1-0.35 g/cm3. Mechanical and hydraulic properties of the permeable carbons with similar cell diameters manufactured by two different processes were compared.
