Keywords： FFC

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 Al_2O_3, Sc_2O_3 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 Al_3Sc particles, which can give another new view for aluminum industry.
