Under optimum conditions determined experimentally. the current efficiency amountedto 70% and the master alloy contained 61% Sr After vacuum distillation or the cathodic product, metallicSr of 98% purity was obtained.展开更多
The results of linear potential sweep experiments show that, in the molten salt systems of NdF3-LiF-CaF2 and NdF3-LiF-CaF2-Nd2O3, the electrochemical reduction of Nd(III) at Mo cathode takes place in two steps. The di...The results of linear potential sweep experiments show that, in the molten salt systems of NdF3-LiF-CaF2 and NdF3-LiF-CaF2-Nd2O3, the electrochemical reduction of Nd(III) at Mo cathode takes place in two steps. The dissolution loss of metallic Nd in fluoride melts under different conditions was determined according to the weight difference of Nd before and after experiments.展开更多
The electromotive force(EMF)was determined by electrochemical method at 760～950℃ for the concen- tration cell:(Mo)Sr|SrCl_2,--Sr sat.||SrCl_2,--xSr|Mo. The dissolution behavior of Sr and alloyed strontium (i.e.Cu--S...The electromotive force(EMF)was determined by electrochemical method at 760～950℃ for the concen- tration cell:(Mo)Sr|SrCl_2,--Sr sat.||SrCl_2,--xSr|Mo. The dissolution behavior of Sr and alloyed strontium (i.e.Cu--Sr or Al--Sr) in molten salt containing SrCl_2 was studied. The electrolysis of SrCl_2 for production of Sr and its alloys(Al-Sr and Cu-Sr) was also conducted on the basis of electrochemical measurement. The disso- lution data so obtained well agree with the results from phase diagram.展开更多
