Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines the development, use, extraction, and recovery of rare earth metals. Rare earth elements (REEs) occupy a key role in daily life in industrial applications. They are one of the critical elements for energy and sustainable growth. REEs are utilized in many modern electrical and electronic devices such as smart phones, computers, LED lights etc. Recovery of the REEs from secondary resources represents a way to meet the growing demand for electronic devices. Because of their rarity, utility, and importance, the recovery, utilization and recycling of rare earth metals is of utmost importance. This book presents both current methods of processing rare earths from primary and secondary sources and new, green routes for their isolation and purification. The book also addresses their utilization, re-use, reduction, and recycling policies that exist globally. Applications in metallurgy, magnets, ceramics, electronics, and chemical, optical, and nuclear technologies are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This volume of the Handbook is the first of a two-volume set of reviews devoted to the rare-earth-based high-temperature oxide superconductors (commonly known as hiTC superconductors). The history of hiTC superconductors is a few months short of being 14 years old when Bednorz and Müller published their results which showed that (La,BA)2CuO4 had a superconducting transition of ~30 K, which was about 7K higher than any other known superconducting material. Within a year the upper temperature limit was raised to nearly 100K with the discovery of an ~90K superconducting transition in YBa2Cu3O7-&dgr;. The announcement of a superconductor with a transition temperature higher than the boiling point of liquid nitrogen set-off a frenzy of research on trying to find other oxide hiTC superconductors. Within a few months the maximum superconducting transition reached 110 K (Bi2Sr2Ca2Cu3010, and then 122K (TlBa2Ca3Cu4O11. It took several years to push TC up another 11 K to 133 K with the discovery of superconductivity in HgBa2Ca2Cu3O8, which is still the record holder today.

Available in PDF, EPUB and Kindle. Book excerpt: Metal oxide-zirconia systems are a potential class of materials for use as structural materials at temperatures above 1900 K. These materials must have no destructive phase changes and low vapor pressures. Both alkaline earth oxide (MgO, CaO, SrO, and BaO)-zirconia and some rare earth oxide (Y2O3, Sc2O3, La2O3, CeO2, Sm2O3, Gd2O3, Yb2O3, Dy2O3, Ho2O3, and Er2O3)-zirconia system are examined. For each system, the phase diagram is discussed and the vapor pressure for each vapor specie is calculated via a free energy minimization procedure. The available thermodynamic literature on each system is also surveyed. Some of the systems look promising for high temperature structural materials.

Available in PDF, EPUB and Kindle. Book excerpt: "In order to develop the thermodynamic database containing rare earth sesquioxides (RE2O3), accurate thermodynamic descriptions of all stable and metastable RE2O3 phases are required. Rare earth sesquioxides have numerous polymorphs, which are (from low to high temperature) the cubic phase (labelled C), the monoclinic phase (B), the hexagonal phase (A), the high temperature hexagonal phase (H), and the high temperature cubic phase (X). However, the thermodynamic property data available for these different polymorphous are insufficient especially for the phase stable at high temperature region and also for metastable forms. In this study, all , , CP (or heat content) and phase transition temperature (Ttr) data available in the literature were collected and critically evaluated for each rare earth sesquioxide based on the experimental procedures and techniques employed. Relationships between , , and Ttr against the ionic radii of the entire rare earth sesquioxide series were then established and missing thermodynamic information was predicted. In general, the enthalpy () and entropy () changes of the C - B, B - A, A - H, and H - X transitions are either scarce or unavailable. For the C - B and B - A transitions, experimental enthalpy data and entropies extracted using the Clausius - Clapeyron relation were collected from the literature and employed together with results obtained from Density Functional Theory (DFT) calculations to estimate the and . Based on the observations from the RE2O3 liquidus in RE2O3 - Al2O3 binary phase diagrams, a small value for A - H and H - X transitions was estimated by applying so - called "limiting slope rule" to ensure smooth liquidus slope change between A and H, as well as H and X phases. Regarding the properties of fusion, the similar "limiting slope rule" was employed that a couple of phase diagram data points were taken near the pure RE2O3 melting points for Hm and Sm estimations. In these ways, the accurate and consistent Gibbs energies of all stable and metastable RE2O3 phases (RE = La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) are prepared. These Gibbs energy data will be ready readily used for the development of a comprehensive thermodynamic database containing rare earth oxides. " --

Available in PDF, EPUB and Kindle. Book excerpt: Work under Contract E(11-1)-1109 and its antecedents has been primarily for the purpose of obtaining detailed thermodynamic, kinetic and structural information on the complex rare earth oxides of praseodymium and terbium. These systems exhibit homologous series of ordered phases, order-disorder transformations, wide-range nonstoichiometric phases, chemical hysteresis in two-phase regions and many other solid state reaction phenomena. Fluorite-related materials of importance to ERDA occur as nuclear fuels, radiation power sources, insulators and solid electrolytes. The rare earth oxides serve directly as model systems for such similar materials and, in a more general sense, they serve as models of solids in general since they exhibit nearly the full range of solid state properties.
