Binary Rare Earth Oxides is the first book in the field of rare earth oxides that provides coverage from the basic science through to recent advances. This book introduces the unique characteristics of the binary rare earth oxides with their chemistry, physics and applications. It provides a comprehensive review of all the characteristics of rare earth oxides, essential for scientists and engineers involved with rare earths, oxides, inorganic materials, ceramics, and structures. The binary rare earth oxides bring us a variety of interesting characteristics. Understanding their fundamental mechanisms builds a bridge between solid-state chemistry and materials science. The book begins with a brief introduction to binary rare earth oxides, their physical and chemical stabilities, polymorphism, crystal structures and phase transformation and the association with current applications. The book goes on to present the band structure of the oxides using several quantum chemical calculations, which belong to a newly developed area in the binary rare earth oxides. Central to this chapter are the characterizations of electrical, magnetic and optical properties, as well as details of single crystal growth and particle preparation methods that have progressed in recent years. Later chapters concentrate on thermo-chemical properties and trace determination techniques. The final chapter contains a variety of useful applications in various fields such as phosphors, glass abrasives, automotive catalysts, fuel cells, solid electrolytes, sunscreens, iron steels, and biological materials. This book is an invaluable resource for materials scientists and solid-state physicists and chemists with an interest in rare earth oxides, as well as advanced students and graduates who require an approach to familiarize them with this field. This book provides guidance through a comprehensive review of all the characteristics of binary rare earth oxides.

The formation of fluorite-type phases was investigated in R2O3-U3O8-O2 systems (where R-La, Sm, Dy, Yb) annealed for 66-85 hr at 1200C, and the solubility limits of the rare earth oxides in uranium octoxide were determined. The U(VI) content and the total uranium content were determined by coulometric analysis at a controlled potential. X-ray phase analysis was carried out by using the powder method with RKD-57 and RKU-86 cameras. The degree of oxidation of uranium changes with the ratio R/U and reaches 6 in samples where R/U=2/1. Thus, the presence of a rare earth oxide increases the stability of the hexavalent state of uranium at high temperatures. Contrary to expectations, the solubility of rare earth oxides in U3O8 was found to be very low (less than 1.5 mol % of RO1.5). (Author).

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.
