Rare Earth-Based Corrosion Inhibitors
Author: Maria ForsythPublisher: Elsevier
ISBN: 0857093584
Category : Technology & Engineering
Languages : en
Pages : 347
Book Description
Corrosion inhibitors are an important method for minimizing corrosion; however traditional inhibitors such as chromates pose environmental problems. Rare earth metals provide an important, environmentally-friendly alternative. This book provides a comprehensive review of current research and examines how rare earth metals can be used to prevent corrosion and applied to protect metals in such industries as aerospace and construction. Chapter 1 begins by examining the important need to replace chromate, and then goes on to discuss the chemistry of the rare earth metals and their related compounds. Chapter 2 considers the techniques that can be used to identify corrosion inhibition mechanisms and to test the levels of protection offered to different metals by rare earth compounds. Subsequent chapters consider in more detail how rare earth elements can be used as corrosion inhibitors in different forms and for different metals. This includes discussion on the potential of rare earth elements for self-healing, tunable and multifunctional coatings. Finally, chapter 10 considers the cost and availability of the rare earths and the potential health and environmental risks associated with extracting them.

Transition Metal and Rare Earth Compounds
Author: Hartmut YersinPublisher: Springer Science & Business Media
ISBN: 3540679766
Category : Medical
Languages : en
Pages : 201
Book Description
Transition metal and rare earth compounds are investigated intensively because of important questions concerning fundamental research problems. More recently also their enormous potential for the development of new materials for photophysical and photochemical applications has been explored. Thus, it is important to focus on a deeper understanding of the elctronic energies, transition prohabilities, intermolecular interactions, etc.. This task has been accomplished by leading researchers in the field. They present introductions into, but also detailed reviews of the current state of knowledge of three different subjects.
Study of Some Rare Earth Compounds

Pages : 128
Book Description
During the past few years, the high pressure structural phase transition in Rare Earth Compounds has been studied extensively. These materials are mostly ionic in nature; crystallize in the rock salt structures at ambient pressure. In the rare earth compounds, the electrons hybridized between two states, which have nearly equal energy. These properties have been correlated with existence of unfilled f electron shell of RE ions, which therefore interact strongly with the lattice. In the present book a theoretical model has been used in order to understand the effect of f- electrons on phase transition, elastic, mechanical and lattice dynamical properties. The necessity of the development of present two body ineriionic potential model and various interactions required essentially for a complete account of the cohesion in RE compound have been described.We have also discussed Breathing Shell Model (BSM) theory to calculate complete phonon spectrum, density of states and specific heat of Neptunium Chalcogenides in this book.

Magnetic Properties of Rare Earth Metals
Author: R. ElliottPublisher: Springer Science & Business Media
ISBN: 1475756917
Category : Technology & Engineering
Languages : en
Pages : 430
Book Description
The rare earths have a unique place among the elements. Although very much alike chemically and in most phy~ical properties they each have very different and striking magnetic properties. The reason, of course, lies in their 4f electrons which determine the magnetic properties but have little effect on other chemical and physical behaviour. Although they are not rare, some indeed are among the more common heavy elements in the earth's crust, the difficulty of separation has meant that their intricate magnetic properties have only recently been unravelled. Now, however, the general pattern of their magnetism is well charted and the underlying theory is well understood. Both are thoroughly summarised in this book. It provides an excellent example of the kind of extensive synthesis which is possible with modem solid state physics. it represents only a high plateau in the ascent to complete understanding. But It will become clear to the reader that while the overall position is satisfactory there are many details still to be elucidated experimentally and much to be done theoretically before all the underlying forces are identified and estimated from a priori calculations. It is hoped that the book will provide a useful stimulus in this direction. It should also be of use to those who are interested in related disciplines, for example the rare earth compounds, or the transition metals. In addition rare earths promise to be important technologically as alloy constituents.
Modern Aspects of Rare Earths and their Complexes

ISBN: 0080536689
Category : Science
Languages : en
Pages : 1005
Book Description
In order to use rare earths successfully in various applications, a good understanding of the chemistry of these elements is of paramount importance. Nearly three to four decades have passed since titles such as The Rare Earths edited by F.H. Spedding and A.H. Daane, The chemistry of the Rare Earth Elements by N.E. Topp and Complexes of the Rare Earths by S.P. Sinha were published. There have been many international conferences and symposia on rare earths, as well as the series of volumes entitled Handbook of Physics and Chemistry of Rare Earths edited by K.A. Gschneidner and L. Eyring. Thus, there is a need for a new title covering modern aspects of rare earth complexes along with the applications. The present title consists of twelve chapters. 1. Introduction2. General aspects3. Stability of complexes4. Lanthanide complexes5. Structural chemistry of lanthanide compounds6. Organometallic complexes7. Kinetics and mechanisms of rare earths complexation8. Spectroscopy of lanthanide complexes9. Photoelectron spectroscopy of rare earths10. Lanthanide NMR shift reagents11. Environmental ecological biological aspects12. Applications The authors studied in schools headed by pioneers in rare earth chemistry, have a combined experience of one hundred and fifty years in inorganic chemistry, rare earth complex chemistry, nuclear and radiochemistry of rare earths and supramolecular chemistry. The present monograph is a product of this rich experience.
