Calcium Production by the Electrolysis of Molten CaCl^sub 2^--Part I. Interaction of Calcium and Copper-Calcium Alloy with Electrolyte

This paper describes the interaction between calcium and molten CaCl^sub 2^ and the solubility of calcium in this melt, depending on the calcium content in the copper-calcium alloy that comes in contact with the molten CaCl^sub 2^. The negative influence of the dissolved calcium on the current effic...

Zusammenfassung:This paper describes the interaction between calcium and molten CaCl^sub 2^ and the solubility of calcium in this melt, depending on the calcium content in the copper-calcium alloy that comes in contact with the molten CaCl^sub 2^. The negative influence of the dissolved calcium on the current efficiency was verified. The negative effects of moisture and CaO impurities on the calcium current efficiency were demonstrated. The dependence of the current efficiency and the purity of the metal obtained by the electrolysis conditions were studied in a laboratory electrolyzer (20 to 80 A).[PUBLICATION ABSTRACT]
