Tlhaloso: Ni307-7 ke electrode e thehiloeng ho nickel e nang le sekoahelo se tlase sa sodium sa haeterojene. Sebelisa DCEP (electrode ea motlakase o tobileng)E na le ts'ebetso e ntle ea ho tjheseletsa ka ho chesa ha arc ho tsitsitseng, ho fafatsa hanyane, ho tlosa slag habonolo,le ho tjheseletsa ho hotle. Tšepe e kentsweng e na le thepa e tsitsitseng ya mechini le ho hanyetsa mafome hantlesepakapaka se nang le oxidizing mochesong o phahameng le se nang le sebabole.
