Tlhaloso e Khutšoanyane:

Boloko ba khabone ba anode bo bolela boloko ba khabone, bo hlahisitsoeng ka petroleum coke le pitch coke e le aggregate le mashala a tar pitch e le binder, e sebelisoang e le thepa ea anode bakeng sa sele ea electrolytic ea aluminium e besitsoeng esale pele. Mofuta ona oa boloko ba khabone o halikiloe 'me o na le geometry e tsitsitseng. Ka hona, e boetse e bitsoa boloko ba khabone ba anode e besitsoeng esale pele, 'me e boetse e bitsoa carbon anode bakeng sa electrolysis ea aluminium.
