中文摘要	the electrochemical reduction of yttrium ion on a molybdenum electrode in a licl-kcl-nacl eutectic melt at 723 k was found to be almost reversible and to proceed by a one-step three electron reaction. the diffusion coefficient d of the y(iii) ion was measured to be (3.3 +/- 0.4) x 10(-6) cm2 s-1 by cyclic voltammetry, (5.0 +/- 0.9) x 10(-6) cm2 s-1 by the rotating disk electrode method, and (7.1 +/- 0.7) x 10(-6) cm2 s-1 by chronopotentiometry. the d values obtained by the latter two methods are in fairly good agreement with each other. the rather low d value obtained by cyclic voltammetry might be attributed to the fact that yttrium metal can dissolve slightly in the chloride melt. the standard potential of y(iii)/y(0) couple was determined to be (-3.174 +/- 0.006) v (vs. cl2/cl-) by open-circuit potentiometry, (-3.15 +/- 0.02) v (vs. cl2/cl-) by the rotating disk electrode method and (-3.16 +/- 0.02) v (vs. cl2/cl) by chronopotentiometry. these three values are in good agreement with each other. several types of ni-y intermetallic compounds were found to be formed on a nickel electrode.
