Graphite electrode and preparation method thereof
The invention relates to a graphite electrode and a preparation method thereof. The graphite electrode comprises a graphite core material and a coating attached to the surface of the graphite core material, wherein the coating is made of a mixture of ceramic and composite metal, the composite metal is composed of metal I and metal II, the metal I is aluminum and/or titanium, and the metal II is at least one selected from tungsten, tantalum, iron, nickel, cobalt, copper and manganese. The graphite electrode is low in resistivity, graphite loss can be obviously reduced, and the graphite electrode has great industrial application prospects.
本发明涉及一种石墨电极及其制备方法，所述石墨电极包括石墨芯材以及附着于石墨芯材表面的涂层，所述涂层的材质为陶瓷和复合金属的混合物，所述复合金属由金属Ⅰ和金属Ⅱ组成，所述金属Ⅰ为铝和/或钛，所述金属Ⅱ选自钨、钽、铁、镍、钴、铜、锰中的至少一种，该石墨电极不仅电阻率低，而且还能够明显降低石墨损耗，极具工业应用前景。
