Volume 19 of Group III (Crystal and Solid State Physics) deals with the magnetic properties of metals, alloys and metallic compounds. The amount available of information in this field is so substantial that several subvolumes are needed to cover it all. Subvolumes III/19a through III/19f treat the intrinsic magnetic properties, i.e. those magnetic properties which depend only on the chemical composition and the crystal structure. So far, subvolumes III/19a, III/19b and III/19c have appeared. Subvolume III/19e is concerned with the magnetic data of the metallic compounds of rare earth elements with main group elements. It is divided into two parts. Part III/19e2 came out last year; part III/19e1 is presented herewith. Data on the properties that depend on the preparation of the samples measured, as for instance, thin films, amorphous alloys or the magnetic alloys used in technical applications, are being compiled in the last subvolumes of III/19: III/19g and III/19h, of which III/19g has already appeared.

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. - Provides a 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 - Includes discussion on the potential of rare earth elements for self-healing, tunable and multifunctional coatings - Considers the cost and availability of the rare earths and the potential health and environmental risks associated with extracting them

The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

This book deals with the rare earth elements (REE), which are a series of 17 transition metals: scandium, yttrium and the lanthanide series of elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium). They are relatively unknown to the wider public, despite their numerous applications and their critical role in many high-tech applications, such as high-temperature superconductors, phosphors (for energy-saving lamps, flat-screen monitors and flat-screen televisions), rechargeable batteries (household and automotive), very strong permanent magnets (used for instance in wind turbines and hard-disk drives), or even in a medical MRI application. This book describes the history of their discovery, the major REE ore minerals and the major ore deposits that are presently being exploited (or are planned to be exploited in the very near future), the physical and chemical properties of REEs, the mineral processing of REE concentrates and their extractive metallurgy, the applications of these elements, their economic aspects and the influential economical role of China, and finally the recycling of the REE, which is an emerging field.

This third volume of the Supplement Series supplying the Main Volumes of the series "Perfluorohalogenoorgano Compounds of Main Group Elements", Part 1 to 9, completes the treatment of the compounds of the Main Group VI elements. It covers sulfur(IV) compounds, sulfonic acids, sulfonic anhydrides, and sulfonates, sulfur(VI) oxides, sulfonyl nitrogen compounds, sulfonyl halides, sulfur(VI) halides, and the compounds of selenium and tellurium. It also includes the perfluorohalogenoorgano compounds of iodine in oxidation states higher than one and contains a formula index for the Supplement Volumes 1, 2, and 3. The Supplement Series will be concluded by the description of the nitrogen compounds. Concept, organization, and selection as to the coverage of the material are the same as in the Main Volumes. Title compounds are newly synthesized ones as well as those compounds already referred to in the Main Volumes and for which new facts have been published. Conventions as to the presentation of the data are given in the prefaces of the Main Volumes. In contrast to the convention for NMR chemical shifts used previously, chemical shifts downfield from the standard are designated as positive, according to the recommendations of the IUPAC Commission on Molecular Structure and Spectroscopy (Pure and Applied Chemistry 29 [1972]625/8, 45 [1976] 217/9). I wish to thank Prof. Dr. Dr. h.c. E. Fluck and his co-workers for their excellent cooperation. I also wish to take the opportunity to express my appreciation to colleagues who assisted me by providing reprints and patents.

Lanthanides are of great importance for the electronic industries, this new book (from the EIBC Book Series) provides a comprehensive coverage of the basic chemistry, particularly inorganic chemistry, of the lanthanoid elements, those having a 4f shell of electrons. A chapter is describing the similarity of the Group 3 elements, Sc, Y, La, the group from which the lanthanoids originate and the group 13 elements, particularly aluminum, having similar properties. Inclusion of the group 3 and 13 elements demonstrates how the lanthanoid elements relate to other, more common, elements in the Periodic Table. Beginning chapters describe the occurrence and mineralogy of the elements, with a focus on structural features observed in compounds described in later chapters. The majority of the chapters is organized by the oxidation state of the elements, Ln(0), Ln(II), Ln(III), and Ln(IV). Within this organization the chapters are further distinguished by type of compound, inorganic (oxides and hydroxides, aqueous speciation, halides, alkoxides, amides and thiolates, and chelates) and organometallic. Concluding chapters deal with diverse and critically important applications of the lanthanoids in electronic and magnetic materials, and medical imaging.
