ELECTROLYTE USED FOR ALUMINUM ELECTROLYSIS AND ELECTROLYSIS PROCESS USING THE ELECTROLYTE |
摘要 |
An electrolyte for aluminum electrolysis employs a pure fluoride salt system and includes the following components by mass percent: 20-29.9% of NaF, 60.1-66% of AlF3, 3-10% of LiF, 4-13.9% of KF and 3-6% of Al2O3, in which the molar ratio of NaF to AlF3 is 0.6-0.995; or the electrolyte includes the following components by mass percent: 30-38% of NaF, 49-60% of AlF3, 1-5% of LiF, 1-6% of KF and 3-6% of Al2O3, in which the molar ratio of NaF to AlF3 is 1.0-1.52. |
