Abstract Scope Molten chloride salts are known to be highly hygroscopic, and thus require dehydration prior to their use as an electrolyte in high temperature electrochemical processes. Thermal dehydration is often used, but incomplete water removal at lower temperatures can result in hydrolysis to form oxides or hydroxides at the higher temperatures required to melt the salt. In this paper, dehydration of LiCl and CaCl<sub>2</sub> will be considered. These salts have been used widely for reduction and electrorefining of actinides. Cyclic voltammetry shows that thermal dehydration of LiCl leads to formation of LiOH, while thermal dehydration of CaCl<sub>2</sub> leads to formation of CaO. The effects of these impurities on various high temperature electrochemical processes will be discussed.
