Molten salts are of considerable significance to chemical technology. Applications range from the established ones, such as the production of aluminum, magnesium, sodium and fluorine, to those as yet to be fully exploited, such as molten salt batteries and fuel cells, catalysis, and solar energy. Molten salts are investigated for different purposes by many diverse techniques. There is a need to keep investigators working in different areas, such as metal production, power sources, and glass industry, aware of progress in various specialties, as well as to familiarize new research workers with the fundamental aspects of the broad field of molten salt _ chemistry. This volume constitutes the plenary lectures presented at the NATO Advanced Study Institute on Molten Salt Chemistry, Camerino, Italy, August 3-15, 1986. The fundamentals and several selected applications of molten salt chemistry were addressed. The major fundamental topics covered at this ASI were the structure of melts, thermodynamics of molten salt mixtures, theoretical and experimental studies of transport processes, metal-metal salt solutions, solvent properties of melt systems, acid-base effects in molten salt chemistry, electronic absorption, vibrational, and nuclear magnetic resonance spectroscopy of melt systems, electrochemistry and electroanalytical chemistry in molten salts, and organic chemistry in molten salts. The applied aspects of molten salt chemistry included the chemistry of aluminum production, electrodeposition using molten salts, and molten salt batteries and fuel cells.

Thermodynamic and Transport Properties of Organic Salts is concerned with the thermodynamic and transport properties of organic salts, namely, pure salts, mixtures, and solutions. The transport properties of pure molten salts and binary mixtures of molten salts with organic ions are given, along with the transport properties of organic salts in aqueous solutions. This book is divided into three sections and opens with a discussion on the statistical treatment and of computer simulation methods for molten salts as well as their results for pressure-volume-temperature (PVT) data. The PVT data for organic molten salts determined experimentally are considered, and the thermal properties as well as the melting mechanism of pure salts are described. A method by which PVT data at high pressure can be estimated from those at low pressure with sufficiently high accuracy is also outlined. The next section deals with salt mixtures, their phase diagrams, and their transport properties. The final section looks at the transport properties of organic salts in aqueous solutions; thermodynamic quantities of micelle formation; and formation of lyotropic liquid crystals by organic salts. Two appendixes showing the structure of the pure solids and the use of the melts in electrochemical studies are included. This monograph will be a useful resource for organic chemists.

The objective of this research is to determine the absolute entropies, heats of formation, and free energies of formation of selected salts in the temperature range of 800 to 1900 deg F. Assembling and testing of apparatus for measuring heat capacities from about 50 deg K to room temperature has been completed, including calibration of thermocouples by comparison with a platinum and with a copper resistance thermometer. This apparatus has been used to determine the absolute entropy of molybdenum hexafluoride vapor at 298.16 deg K. The result, 79.7 +- 0.6 calories/mole deg C, agrees well with that calculated from its spectrum, 80.05 cal/mole deg C.A solution calorimeter has also been assembled and tested. By comparing the heat of solution in aqueous sodium hydroxide of molybdenum hexafluoride with that of the oxide, the delta H of formation of the fluoride was found to be -392.2 cal/mole at 298.16 deg K. These data, together with other data extant in the literature, allow calculation of the desired thermodynamic functions over the temperature range of interest.

Molten Salts Handbook focuses on the features, properties, and structure of molten salts. This book presents several topics in annotated bibliographic table form, including phase equilibria, chemical syntheses, and molten salt electrolytes. Organized into six chapters, this book starts with a tabular presentation of data of the physical properties, thermodynamic properties, electrochemical properties, practical features, as well as spectroscopy and structure of molten salts. This text then illustrates the design features of different experimental assemblies and provides information on the technique through a liberally annotated bibliography. Other chapters provide a chemical index, which offers a ready guide to the status of data over the entire range of interests. This book presents as well the properties of viscosity, density, surface tension, refractive index, and electrical conductance for different compounds as single salt melts. This book is a valuable resource for scientists and researchers from diverse fields, including theoretical and applied electrochemistry, inorganic coordination chemistry, and transition metal chemistry.

Molten salts are investigated by very diverse techniques and for differ ing purposes, and the results are reported in widely scattered journals. There is a need to keep investigators aware of progress in other specialties and to provide students with source and background material. Advances in Molten Salt Chemistry hopes to fill these needs by providing reviews of recent progress presented, insofar as is reasonable, with enough background material and commentary to be comprehensible to a nonspecialist. We prefer a discussion of underlying principles, to the extent that they are known, and we encourage authors to comment critically on the reliability of data, the utility of models, and the cogency of ideas and theories. We take a broad vie~ of the suitability of topics for inclusion in this series. Both fundamental and technological advances have a place here, as do studies on materials related to molten salts (like liquid silicates, very concentrated aqueous solutions, solutions of salts in liquid metals, and solid electrolytes). We intend this series to serve the needs of those who investigate or use molten salts. We welcome suggestions of topics and suitable authors, as well as comments on the strengths and shortcomings of what is published.
