Beschreibung
Zusammenfassung:	A cathode component for a Hall aluminum cell is economically produced from a mixture of a carbon source, preferably calcined petroleum coke, and optionally calcined acicular needle petroleum coke, calcined anthracite coal; a binder such as pitch including the various petroleum and coal tar pitches; titanium dioxide, TiO2; and boric acid, B2O3 or boron carbide, B4C; forming said mixture into shapes and heating to a TiB2-forming temperature.
