Brown coal and its char were investigated as substitutes for petroleum coke in the manufacture of anodes for Hall-Heroult cells. The char, which had been densified by several techniques, was made into compacts with various binders and the anodic consumption determined during electrolysis. The results were an improvement on previous work, but the anodes still fell short of acceptability for use in aluminium smelters because of intractable microporosity. Some options for future development have been discounted.
