This book summarizes recent progresses in inorganic fluorine chemistry. Highlights include new aspects of inorganic fluorine chemistry, such as new synthetic methods, structures of new fluorides and oxide fluorides, their physical and chemical properties, fluoride catalysts, surface modifications of inorganic materials by fluorination process, new energy conversion materials and industrial applications. Fluorine has quite unique properties (highest electronegativity; very small polarizability). In fact, fluorine is so reactive that it forms fluorides with all elements except with the lightest noble gases helium, neon and argon. Originally, due to its high reactivity, fluoride chemistry faced many technical difficulties and remained undeveloped for many years. Now, however, a large number of fluorine-containing materials are currently produced for practical uses on an industrial scale and their applications are rapidly extending to many fields. Syntheses and structure analyses of thermodynamically unstable high-oxidation-state fluorides have greatly contributed to inorganic chemistry in this decade. Fluoride catalysts and surface modifications using fluorine are developing a new field of fluorine chemistry and will enable new syntheses of various compounds. The research on inorganic fluorides is now contributing to many chemical energy conversion processes such as lithium batteries. Furthermore, new theoretical approaches to determining the electronic structures of fluorine compounds are also progressing. On the industrial front, the use of inorganic fluorine compounds is constantly increasing, for example, in semi-conductor industry. "Advanced Inorganic Fluorides: Synthesis, Characterization and Applications" focuses on these new features in inorganic fluorine chemistry and its industrial applications. The authors are outstanding experts in their fields, and the contents of the book should prove to be of valuable assistance to all chemists, graduates, students and researchers in the field of fluorine chemistry.

This volume reviews the preparation, structures, physicochemical properties and applications of graphite fluorides, mainly based on the results obtained by the authors. Their interest in graphite fluorides stemmed from research on the ``anode effect'''', in electrolytic production of fluorine gas in KF.2HF melt using carbon electrodes.The formation of a thin graphite fluoride film on carbon anodes made it difficult to continue the electrolysis of KF.2HF at a high current density. To elucidate this phenomenon studies on graphite fluoride were initiated. In the course of these systematic studies, the use of graphite fluoride in high-energy batteries became successful: a new graphite fluoride (C2F)n was found; and another fluorineographite intercalation compound with ionic bonding, CxF, was synthesized. During this research it was established that CxF is closely associated with the ``anode effect''''.The book will be of interest to all those involved in the study and research of graphite fluorides, particularly fluorine chemists, electrochemists, and fluorine and battery companies.

Translated from Japanese, this book details some of the most interesting developments of the last few decades in the field of fibre manufacture. Many of these have been the result of intensive study in industry and research institutes in Japan - the country at the forefront of research in fibre spinning technology.
