| Abstract: | The effects of additive lithium salts on aluminum electrolysis are reported. The main advantages of additive lithium salts to aluminum electrolysis are that increasing electrical conductivity of melts, decreasing the melting point of electrolyte, decreasing aluminum dissolved in cryolite melts, decreasing polarixation voltage, depressing vapour pressures of electrolyte and prolonging life of cathode. One assumption is put forward that emormous economic and environmental benefits will he acquired when lithium salts and other additives are appropriately added to the electrolysis cell. |
| Keywords: | aluminum electrolysis lithium salts(LiF/Li_2CO_3) additive |
