Title:
A PRODUCTION METHOD FOR SCANDIUM METAL OR AL-SC ALLOYS USING ELECTROLYSIS METHOD FROM SCANDIUM SALT MIXTURES PREPARED BY ADDING OF CACL2 AND/OR MGCL2 COMPOUNDS TO SCF3 COMPOUND OBTAINED FROM SCANDIUM COMPOUND IN THE FORM OF (NH4)2NASCF6
Document Type and Number:
WIPO Patent Application WO/2019/083471
Kind Code:
A3
Abstract:
The invention relates to a production method for scandium metal in pure or alloy form using molten salt electrolysis or electrolysis method from scandium salt mixtures prepared by adding CaCI2 and/or MgCI2 salts to ScF3 compound, in order to lower its melting temperature, which is obtained by reacting the initial scandium compound, having the form of (NH4)NaScF6, with HCI in aqueous medium and removing (NH4) and Na with CI from its structure
