Pre-baked carbon anode with high conductivity and oxidation resistance and preparation method of pre-baked carbon anode
The invention relates to the technical field of aluminum electrolysis carbon anodes, in particular to a prebaked carbon anode with high conductivity and oxidation resistance and a preparation method of the prebaked carbon anode. The raw materials of the prebaked carbon anode comprise dry materials with multiple particle sizes and a binder, and the total weight m1 of the dry materials with multiple particle sizes and the weight m2 of the binder meet the relational expression: m1: m2 = (82: 18)-(88: 12); wherein the raw materials of the dry material comprise calcined petroleum coke with multiple granularities and conductive carbon materials with multiple granularities, and the calcined petroleum coke and the conductive carbon materials meet the following relational expressions: m3: m4 = (80-95): (5-20), and m31: m42 = m3: m4. According to the prebaked carbon anode, the conductivity and the oxidation resistance can be synchronously improved.
