| Popis: | The mechanisms of the reduction of K[sub 2]WCl[sub 6] in molten LiCl-KCl eutectic was studied using cyclic voltammetry, chronopotentiometry, and controlled potential coulometry over a temperature range of 400 to 500 C and a WCl[sup 2-][sub 6] concentration of 0.0005 to 0.005 mol/liter. A single irreversible wave attributed to the reduction of W(IV) to W(III) was observed. The experimental results further indicated the process to be diffusion controlled with n[approximately]1.3 and [alpha] ranging from 0.85 to 0.95. W(III) is soluble at 500 C and insoluble, but still electroactive, below 460 C. |
