摘　　要：以SrCl2为原料,在70%SrCl2-29%KCl-1%SrF2体系中电解生产Al-Sr合金。考察了电解温度、电流密度和电解时间等条件对电流效率和合金锶含量的影响。通过控制工艺条件,可以生产锶含量在0～10%的Al-Sr合金,其物相主要为Al与Al4Sr。A1-Sr alloy was prepared via molten salt electrolysis process in 70 %SRC12-29%KCI-1 %SrF2 sys-tem with SrC12 as raw material. The effects of electrolysis temperature, electrolysis time, current density on current efficiency and Sr content of A1-Sr alloy were studied. The results show that A1-Sr alloy with Sr content of 0-10% could be prepared by adjustment of technological conditions. The main mineralogical phases of the A1-Sr alloy are A1 and A14Sr.
