Abstract: The invention concerns a foam consisting of at least 70 wt. % of carbon, having an average cell size more than 30 mu m, porosity between 35 % and 99.7 %, a percentage of open cells higher than 90 %, and comprising linking elements between the cells, which, viewed in cross-section, form a triangle with inward-curving sides. Inside the surface of the cross-section, the sum of the surfaces having a cavity constitutes less than 5 % of the total cross-sectional area of the linking elements. The invention also concerns the use of said foams consisting for the major part of carbon in electrical and electrochemical applications, in the form of filtering material, heat insulation material, support material, storage material and as starting material for other transformations. The invention further concerns a method for producing a foam consisting of at least 70 wt. % of carbon, by pyrolizing synthetic foams. Said method is characterized in that the synthetic foams used contain at least 30 wt. % of a polymer material having a nitrogen content higher than 6 wt. %, and having a porosity between 20 and 99 %, as well as a percentage of open cells higher than 1 %.
