  • Electrolyte for obtaining melts using an aluminum electrolyzer
    Patent number: 10975484
    Abstract: The invention concerns non-ferrous metallurgy, in particular the composition of an electrolyte for electrically obtaining aluminum by the electrolysis of fluoride melts. The electrolyte proposed contains, in % by weight: sodium fluoride 26-43, potassium fluoride up to 12, lithium fluoride up to 5, calcium fluoride 2-6, alumina 2-6, aluminum fluoride and admixtures—the remainder. The technical result is to increase the solubility of alumina in the electrolyte at a temperature of 830-930° C. In the electrolyte being applied for, the carbon and inert electrode materials are not destroyed, and the use of special methods to purify the aluminum of melt components is not required.
