Molten salts and fused media provide the key properties and the theory of molten salts, as well as aspects of fused salts chemistry, helping you generate new ideas and applications for fused salts.

Molten Salts Chemistry: From Lab to Applications examines how the electrical and thermal properties of molten salts, and generally low vapour pressure are well adapted to high temperature chemistry, enabling fast reaction rates. It also explains how their ability to dissolve many inorganic compounds such as oxides, nitrides, carbides and other salts make molten salts ideal as solvents in electrometallurgy, metal coating, treatment of by-products and energy conversion.

This book also reviews newer applications of molten salts including materials for energy storage such as carbon nano-particles for efficient super capacitors, high capacity molten salt batteries and for heat transport and storage in solar plants. In addition, owing to their high thermal stability, they are considered as ideal candidates for the development of safer nuclear reactors and for the treatment of nuclear waste, especially to separate actinides from lanthanides by electrorefining.

Henri Groult

Henri Groult is Director of Research of CNRS-UPMC-ESPCI UMR 7612, University of Pierre and Marie Curie (Paris 6) in France. He has devoted his research life to fluorine chemistry, electrochemistry, and molten salt chemistry. His main research subjects are electrolytic production of fluorine gas, fluorine compounds for primary and secondary lithium batteries, and electrochemical properties of molten fluorides and chlorides. He has obtained interesting results on fluorine evolution reaction on carbon electrodes, discharge behavior of carbon-fluorine compounds, charge/discharge characteristics of metal fluorides, and electrochemical properties of molten salts. On these subjects, he published more than 100 papers and 7 books. His activity has played an important role in fluorine chemistry in France. He has served as Director of the French Network of Fluorine, Chairman of the 17th European Symposium on Fluorine Chemistry (Paris, July 2013), and Editorial board of J. Fluorine Chemistry.

"Editors Lantelme…and Groult…present this compilation of research on molten salt chemistry and its applications, especially in high-temperature industrial processes. The first few chapters are allocated to modeling, spectroscopy, and thermodynamics of molten salt systems, followed by varied applications. Many chemical families are covered, including halides, carbonate-oxide systems, rare-earths, low-abundance transition metals, lithium compounds, and radioactive heavy elements…"--Reference & Research Book News, December 2013
