Abstract: The freezing points of cryolite-alumina melts with the addition of AIF3,CaF2,MgF2 and LiF were measured.It was found that there was a wide range of lower freezing points below 800℃.Various physico-chemical and electro-chemical properties at 30℃ above the correspond- ing freezing points were measured.Current efficiences in a laboratory bench scale 100A cell were high(85～90% at 800～900 C),was low.It is assumed thataluminium electrolysis may be carried out at 800～900 C with lower energy consumption.
