PRODUCTION METHOD FOR SCANDIUM METAL AND AL-SC ALLOYS VIA ELECTROLYSIS OF FLUORINATED SCANDIUM SALTS OBTAINED BY THE CALCINATION OF SCANDIUM COMPOUND IN THE FORM OF (NH4)2NASCF6

摘要

The invention relates to scandium metal obtained in its pure or alloy form, by removing (NH4) form via calcining the initial scandium compound in (NH4)2NaScF6 form and via molten salt electrolysis of fluorinated scandium compounds in NaScF4 and Na3ScF6 forms that resulted after the calcination process.
