摘 要：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.
