PURPOSE:To provide a porous glassy carbon containing interconnected fine pores and having excellent mechanical strength, corrosion resistance, etc. CONSTITUTION:An aqueous solution containing (A) 1pt.wt. of a precondensate of an aromatic hydrocarbon compound having phenolic hydroxyl group (e.g. phenol) and an aldehyde and (B) 2.5-10pts.wt. of an inorganic salt (e.g. ZnCl2) and having a viscosity of 100-100,000 poise is poured into a proper mold, heated at 50-200 deg.C while suppressing the evaporation of water, and cured while separating the inorganic salt from water. The cured material is washed to remove the inorganic salt, optionally dried, and calcined at >=800 deg.C in a non-oxidizing atmosphere to obtain the objective glassy carbon having a bulk density of 0.3-0.8g/cm<3> and an average pore diameter of <=10mum and having three- dimensional network structure containing interconnected pores. |
