Abstract

<PICT:1068801/C6-C7/1> In an electrolytic alumina reduction cell having a pot shell and shell lining for containing the bath constituents, the cathode comprises a collector bar formed by a graphite block 21 terminating within the shell lining and a body of refractory hard metal 25, directly bonded to the terminal end of the graphite block such that it contacts the pad of molten aluminium when in operation. The junction between the refractory hard metal and the graphite block may be surrounded by a refractory sleeve 26. The block 21 may be provided with a groove 22 into which a steel rod 23 is mounted by pouring molten cast iron into the groove about the rod, the assembly being mounted in the cell such that the graphite block contacts an insulating layer between the pot shell and lining, and the rod 23 extends through to the exterior of the shell.
