Abstract. The electrochemical behaviour of melts containing carbamide urea; CO(NH 2) 2 at inert electrodes and the anodic dissolution of niobium, tantalum and titanium in carbamide-ammonium and alkali halide melts, as well as the structure of the complex ions formed, have been studied by electrochemical and spectroscopic methods. In carbamide-containing melts, all metals are : N. Tumanova, O. Boyko, N. Buryak, S. Kochetova. Nickel is widely applied as structural material in molten salts owing to its high corrosion resistance, including a use in sodium-thermic production of tantalum powders. In this connection it is of interest to consider its behaviour in melts containing tantalum : E. Matychenko, V. Novichkov.

Abstract. This paper reviews all the characteristics of surface coating by refractory metals or alloys including Molten Salts Electrodeposition: Selection of the fluorides as electrolyte; experimental conditions of obtaining massive coatings or alloys; applications of the coatings, focused on the preparation of electrode materials. Abstract. Octahedral ionic species are known to exist in molten chloride mixtures containing rare earth as well as molten alkali metal chlorides containing UO 2 2 + ions. This phenomenon can be utilized in pyrochemical reprocessing of nuclear spent fuels (MOX codeposition) in which candidate molten salt solvent systems to stabilize UO 2 2 + and/or PuO 2 2 + ions were proposed to be molten CsCl. B.A. Baker, in Shreir's Corrosion, Molten Salts. Molten-salt technology is critical for several industries. 30 As with molten metals, molten salts are utilized in nuclear and solar energy systems as a medium for heat transfer and storage because of high thermal conductivity and heat capacity. A mixture of sodium and potassium nitrates has been used for energy storage in solar. Electrochemical processing is used extensively in the primary extraction of metals (electrowinning), the purification and recycling of metals (electrorefining), and the formation of metal coatings (electroplating). With respect to the refractory metals, electrochemical processing is conducted almost exclusively in nonaqueous media, predominantly in molten salts.

Behaviour of oxygen reduced species in molten Na2CO3-K2CO3 eutectic at °C: correlation with the oxidative coupling of methane CASTRILLEJO Y., FERRY D., GARCIA A., PARDO R., SANCHEZ-BATANERO P Chemical and electrochemical behaviour of tin ions in ZnC^-xNaCl molten salts CHERRAT E., BENSLIMANE K., LANTELME F., CHEMLA M   For molten salt applications, the gases evolved typically originate from the halide salts (e.g., Cl 2 (g), F 2 (g), and Br 2 (g)) or dissolved oxides (e.g., O 2 (g), CO(g), and CO 2 (g)). In many cases, the gases evolved at an electrode can cause severe corrosion with the electrode materials and the materials of construction of the experimental. E.G.
