Paper or paperboard enriched with carbon comprises at least one fiber material and at least one filler as carbon, where: the content of carbon is at least 15 vol.%, related to the solid volume of paper or paperboard and the total filler content of all existing filler is 30-90 wt.%, related to the dry weight of paper or paperboard or is 25-90 wt.%, related to the solid volume of paper or paperboard. Independent claims are included for: (1) a method for the production of a carbon-enriched paper or paperboard comprising mixing the fiber material and the filler containing the carbon in a solvent to a slurry, and processing the slurry to a paper and/or the paperboard; (2) a method for the pyrolysis of paper or paperboard, comprising pyrolysing the paper or the paperboard produced in the form of a green body; (3) a pyrolysated paper or paperboard produced by the method of pyrolysis of paper or paperboard; (4) a method for sintering of the paper or paperboard or pyrolysated paper or paperboard, comprising sintering the paper or the paperboard at 1200[deg]C, preferably over 1400[deg]C; (5) a method for infiltrating the paper or paperboard enriched with carbon or the pyrolysated paper or paperboard comprising infiltrating the paper or paperboard with a liquid metal; and (6) a ceramic body produced by the method of infiltrating the paper or paperboard enriched with carbon or the pyrolysated paper or paperboard. |
