Abstract

The present invention relates to an electrolyte used for aluminum electrolysis and an electrolysis process using the electrolyte. The electrolyte of the present invention employs a pure fluoride salt system and consists of the following mass percent of constituents: 20% to 29.9% of NaF 60.1% to 66% of A1F 3% to 10% of LiF 4% to 13.9% of KF and 3% to 6% of AlO where the molar ratio of NaF to AlF is between 0.6 and 0.995; or consists of the following mass percent of constituents: 30% to 38% of NaF 49% to 60% of AlF 1% to 5% of LiF 1% to 6% of KF and 3% to 6% of A1O where the molar ratio of NaF to AlF is between 1.0 and 1.52. The electrolyte provided in the present invention is provided with a reduced primary crystallization temperature and improved solubility of aluminum oxide while the electrolyte is provided with an increased electric conductivity. The electrolyte of the present invention provides improved effects of reduced energy consumption increased current efficiency and improved working environment during the electrolysis process.
