许多类型的电极反应发生在熔融盐中，但相对于水溶液，人们对其动力学和机理知之甚少。在概述之后，详细讨论了金属和非金属在卤化物和氧-阴离子熔体中的阴极沉积，包括金属沉积的结构与相应的电化学参数的关系。对于液态金属沉积，非常快速的电荷转移步骤主导了整个反应的行为。这一现象与金属-熔盐界面结构有关。对于单步法制备的固体金属沉积层，人们感兴趣的焦点是它们的成核和生长。如果这些沉积是由过渡金属离子的多步过程产生的，那么化学成分往往掩盖了结构现象。最后，对高温电极反应研究的前景进行了展望。
Many types of electrode reaction occur in molten salts but, relative to aqueous solutions, little is known concern ing their kinetics and mechanisms. After a general survey, detailed attention is given to the cathodic deposition of metals and non-metals from halide and oxy-anionic melts, including the dependence of the structures of the metallic deposits on the corresponding electrochemical parameters. For liquid metal deposits the very rapid charge trans fer steps dominate the behaviour of the overall reaction. This phenomenon is related to the metal-molten salt interfacial structure. For solid metal deposits produced by single step processes, the focus of interest is their nucleation and growth. If these deposits are produced by multistep processes from transition metal ions the chemical com plications often obscure the structural phenomena. Finally, future prospects for high temperature elec trode reaction studies are cited and discussed.
