MIXTURES OF METALS WITH MOLTEN. SALTS

摘要

A review is presented of various types of solutions of metals in molten salts, especially in their own molten halides. With relatively little reference to the older liter¬ature, the progress made in the last 20 years is discussed. Roughly, the solutions are classified into two groups: The metal may retain, to some degree, its metallic properties in the solution, or it may lose them through strong interaction with the salt solvent. The alkali-metal systems are typical examples of the former type, while solutions of cadmium or bismuth represent the second. Equilibrium phase diagram data are presented in detail for many metal-salt systems. These include critical solution temperatures, that is, tem¬peratures above which metal and salt are miscible in all proportions.
