A fired fireproof ceramic body is based on metal oxides, in particular CaO, MgO and/or Al2O3 It contains 1.0 to 12% residual carbon content and is made by mixing a carbonaceous component e.g. graphite into a block mixture of the oxide, binding agent and water, shaping the mixture and firing it under reducing conditions at 1400 DEG to 1700 DEG C. |
