Cathodic processes at TiB2/C-composite electrodes during aluminium electrolysis

Research progress in TiB2 wettable cathode for aluminum reduction

“…Their compressive strength was 14.4 MPa to 47 MPa, and less sodium was present on TiB 2 areas than on carbon areas in specimens after electrolysis. The literature 16,17 reported that wetting of TiB 2 -C composite by liquid aluminum occurred after an immersion time of 6 hours, and discussed the chemical stability of TiB 2 particles in molten aluminum and bath as well as the cathodic process. The results showed that Al 2 O 3 dissolved in bath enhanced the dissolution of TiB 2 .…”
