摘　　要：研究了氯化钠、氯化钠－氯化钾、氯化镁－氯化钠－氯化钾熔体系中碱金属的析出行为．研究表明：由于去极化作用．碱金属析出电位远正于其热力学析出电位．Study was carried out on the deposition of alkali metal during the electrolysis of NaCl, NaCl KCl and MgCl 2 NaCl KCl melts by using galvanostat, potentiostat and voltammetry. It was found that alkali metal deposited at the potential much more positive than its thermodynamic potential owing to depolarization effect. During electrolysis of MgCl 2 alkali metal codeposited with magnesium even at the normal concentration of MgCl 2, and the lower the concentration of MgCl 2 and the more negative the applied potential, the stronger the alkali metal deposition.
