FIELD: carbon materials. ^ SUBSTANCE: invention concerns production of polymer material, which can be employed to manufacture construction-destination porous carbon articles. Polymer composition is filled with hardened phenol-formaldehyde resin and powder-like vanadium complex VO(C36H49O5N2) formed when vanadium is recovered from exhausted process solutions produced in processing of ferrous-metallurgy charge slags as product of reaction between metavanadate and bis-amino-phenol-formaldehyde oligomer. Composition also includes lubricant. Proportions of constituents are the following, wt %: pulverized bakelite 36-43.8, hardened phenol-formaldehyde resin 36-43.8, vanadium complex 10-25, and lubricant 2.4-3.0. ^ EFFECT: increased strength of porous carbon articles. ^ 1 tbl, 7 ex |
