摘要
以LiF-YF3二元熔盐体系为电解质,以镍棒为阴极,以Y2O3为原料,使用自耗阴极电解法制备了成分稳定的Y-Ni合金。同时,考察了电解温度和阴极电流密度对合金成分、电流效率的影响,并对电解产品进行了XRD、SEM-EDS表征。结果表明,在实验条件下,可以生产Y含量为48%~50%(质量分数)的Y-Ni合金,电流效率可达到85%以上,合金相以YNi和YNi2为主,且成分均匀。
The Y-Ni alloys with stable composition were prepared by self-consuming cathode electrolysis in LiF-YF3 molten salt system,with Ni rod as cathode and Y2O3 as raw material.Meanwhile,the effects of electrolytic temperature and cathode current density on alloy composition and current efficiency were studied.The microstructure and composition of the samples were carried out by XRD and SEM-EDS.The results showed that Y-Ni alloy with 48%~50%yttrium could be produced under the experimental conditions,and the current efficiency could reach above 85%.The uniform alloy phases were dominated by YNi and YNi2.
