摘　　要：本文研制了一种新型固体阴极材料，即以石墨为基底的ＴｉＢ２复合涂层。初步研究表明，这种涂层与基底石墨粘结牢固，机械性能良好。我们期望把它做成三层液铝电解精炼槽的固体阴极，从而为降低极距、大幅度节省电能创造条件。A new solid cathode,TiB 2 composite coating based on graphite has been invented Preliminary study indicates that the glutinous property between coating and graphite is nice,and the mechanical intensity of the coating is high The new cathode is expected to be used for lowering the distance between the two electrodes of three-layer aluminium electrolytic refinement and for saving electricity largely
