Поскольку в солевых расплавах пол ризаци имеет только концентрационный характер , то справедливо выражениеnor DES. For high-temperature cells of a special design, the value of Kom can be reduced to a negligible minimum. Then the overlap range will be determined only by the value of U. Since in salt melts polarization has only a concentration character, the expression

При величине заданного потенциала, перекрывающей потенциал вьщелени конкурирующего компонента на 0,05-0,50В, требуема избирательность может быть обеспечена лишь при об зательном прекращении электролиза в момент стабилизации тока.

Провод т потенциостатическое растворение церий-алюминиевых сплавов ( SA 1 см ) в электролите КС -NaCFor the range of temperatures from 623 to 1173 ° K and the possible valence of released metals Z 1-4, which is practically used in the electrolysis of molten salt means, the overlap range will be 0.05-0.50 V. When the value of a given potential, which overlaps the potential of the competing component at 0.05-0.50 V, the required selectivity can be ensured only with a mandatory cessation of electrolysis at the moment of current stabilization. At the same time, as it grows, it increases and ..Q Example. Potentiostatic dissolution of cerium-aluminum alloys (SA 1 cm) in electrolyte KS -NaC
