Abstract:Cathode coating TiB2,carbon fibre and therm osetting binder were coated on the matrix of the cathode in aluminium reduction cell to prepare aluminium werrable cathode surface.By cure and carbonization,this coating wa characterized by strong bonding to cathode matrix and good thermal expansion match.NaF could be saved by 250~300kg when TiB2 coating was applied in a cell;current efficiency of the test froup wa 89.54%, which was 1.44% higher than that of compared group, and energy saving was 175~211kW·h/t Al.
Key words: aluminium reduction cell TiB2 TiB2-coating cathode
