| description | There is provided a cathode carbon block for aluminum smelting having low electrical resistivity and high thermal conductivity to improve the energy efficiency in an aluminum reduction cell and a process for production thereof. There is also provided a cathode carbon block for aluminum smelting having improved wettability with aluminum melt and longer life by reducing the rate of electrochemical erosion by an electrolytic bath, as well as a process for production thereof. In the mixing step, materials are mixed at a mixing ratio of 64 to 97% of carbon raw material to 3 to 36% of titanium carbide. The proportion of titanium carbide is 5 to 100% in the raw material composition having a particle size of 1 mm or less. In the kneading/forming step, an organic binder is added to the mixture after the mixing step, and kneaded and formed. In the baking step, the formed product is baked. In the graphitization step, the baked product after being baked in the baking step is graphitized at 2400 to 3000 C. |
