Preparation of Al3Sc Intermetallic Compound by FFC Method

Abstract

Abstract:

The FFC Cambridge process is a direct electrodeoxidation process used to reduce metal oxides for metals or alloys in molten salts. Al-Sc compound oxides are used as a precursor which formed upon blending and sintering Al₂O₃, Sc₂O₃ and Al powders and are successfully reduced by using the FFC Cambridge process at 973 K with a constant cell voltage of −3.2 V. This method is applied to the preparation of fine Al3Sc particles, which can give another new view for aluminum industry.

Key words: FFC, Scandium, Aluminum, Al alloy, Al₃Sc, Electrowinning
