Electrochemical co-reduction of Y(Ⅲ)and Al(Ⅲ)in a fluoride molten salt system and electrolytic preparation of Y-Al intermediate alloys
文献摘要：
In this study,a molten salt co-reduction method was proposed for preparing Y-Al intermediate alloys and the electrochemical co-reduction behaviors of Y(Ⅲ)and Al(Ⅲ)and the reaction mechanism of intermetallic compound formation were investigated by transient electrochemical techniques.The results show that the reduction of Y(Ⅲ)at the Mo electrode is a reversible electrochemical process with a single-step transfer of three electrons,which is controlled by the mass transfer rate.The diffusion coefficient of Y(Ⅲ)in the fluoride salt at a temperature of 1323 K is 5.0238×10-3 cm2/s.Moreover,the thermodynamic properties associated with the formation of Y-A1 intermetallic compounds were estimated using a steady-state electrochemical method.Y-Al intermediate alloy containing 92 wt％yttrium was prepared by constant current electrolysis at 1323 K in the LiF-YF3-AlF3-Y2O3(6 wt％)-Al2O3(1 wt％)system at a cathodic current density of 8 A/cm2 for 2 h.The Y-Al intermediate alloy is mainly composed of α-Y2Al and Y phases.The development and application of this innovative technology have solved major technical problems,such as a long production process,high energy consumption,and serious segregation of alloy elements at this stage.
