Book Description
Rare metals play an important role in the development of major branches of industry, such as vacuum equipment, semiconductor electronics, nuclear power and rocket production, as well as in the production of special steels and hard, refractory and corrosion-resistant alloys.Rapid development and improvement in the production of rare metals took place in the ten years which have elapsed since the publication of the first edition of this book. These ten years have witnessed the beginning of large-scale production of titanium, zirconium, and germanium, and a significant increase in the production volume; new, improved methods for the separation and purification of metals and compounds (ion-exchange, extraction, crystallization methods) as well as arc and electron-beam melting processes for metals were developed. This made it necessary to rewrite most of this book.In view of the growing importance of the lanthanides and rhenium, chapters on these metals were also included. At the same time, we decided to dispense with the chapters on lead and antimony, since these are not usually listed as rare metals. In describing the metallurgy of each metal, much attention was paid to its physicochemical nature and to the practical operations involved in the main technological processes for the production of its chemical compounds and of the pure metal.This book is a textbook for students specializing in the metallurgy of the rare metals. It is assumed that the student is familiar with the physicochemical fundamentals .of metallurgy, ore dressing, metallurgical furnaces, and processes and apparatus used in extractive metallurgy. The description of standard equipment (leaching apparatus, thickeners, filters, comminution installations, etc.) has accordingly been omitted. The references are grouped together at the end of the book.

Book Description
The resources race is on. Powering our digital lives and green technologies are some of the Earth's most precious metals -- but they are running out. And what will happen when they do? The green-tech revolution has been lauded as the silver bullet to a new world. One that is at last free of oil, pollution, shortages, and cross-border tensions. Now updated after several years of research across a dozen countries, this book cuts across conventional green thinking to probe the hidden, dark side of green technology. By breaking free of fossil fuels, we are in fact setting ourselves up for a new dependence -- on rare metals such as cobalt, gold, and palladium. They are essential to electric vehicles, wind turbines, solar panels, our smartphones, computers, tablets, and other everyday connected objects. China has captured the lion's share of the rare metals industry, but consumers know very little about how they are mined and traded, or their environmental, economic, and geopolitical costs. The Rare Metals Waris a vital exposé of the ticking time-bomb that lies beneath our new technological order. It uncovers the reality of our lavish and ambitious environmental quest that involves risks as formidable as those it seeks to resolve.

Book Description
"Rare Earth Frontiers is a timely text. As Klinger notes, rare earths are neither rare nor technically earths, but they are still widely believed to be both. Although her approach focuses on the human, or cultural, geography of rare earths mining, she does not ignore the geological occurrence of these mineral types, both on Earth and on the moon.... This volume is excellently organized, insightfully written, and extensively sourced."―Choice Drawing on ethnographic, archival, and interview data gathered in local languages and offering possible solutions to the problems it documents, this book examines the production of the rare earth frontier as a place, a concept, and a zone of contestation, sacrifice, and transformation. Rare Earth Frontiers is a work of human geography that serves to demystify the powerful elements that make possible the miniaturization of electronics, green energy and medical technologies, and essential telecommunications and defense systems. Julie Michelle Klinger draws attention to the fact that the rare earths we rely on most are as common as copper or lead, and this means the implications of their extraction are global. Klinger excavates the rich historical origins and ongoing ramifications of the quest to mine rare earths in ever more impossible places. Klinger writes about the devastating damage to lives and the environment caused by the exploitation of rare earths. She demonstrates in human terms how scarcity myths have been conscripted into diverse geopolitical campaigns that use rare earth mining as a pretext to capture spaces that have historically fallen beyond the grasp of centralized power. These include legally and logistically forbidding locations in the Amazon, Greenland, and Afghanistan, and on the Moon.

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

Book Description
This excellent report was released in October 2018. America's manufacturing and defense industrial base ("the industrial base") supports economic prosperity and global competitiveness, and arms the military with capabilities to defend the nation. Currently, the industrial base faces an unprecedented set of challenges: sequestration and uncertainty of government spending; the decline of critical markets and suppliers; unintended consequences of U.S. Government acquisition behavior; aggressive industrial policies of competitor nations; and the loss of vital skills in the domestic workforce. Combined, these challenges - or macro forces - erode the capabilities of the manufacturing and defense industrial base and threaten the Department of Defense's (DoD) ability to be ready for the "fight tonight," and to retool for great power competition. The following report explains the macro forces impacting the industrial base, identifies primary categories of risk, illustrates impacts within sectors, and provides recommendations for mitigation.I. Executive Summary * II. Introduction * III. Methodology * IV. An Overview of America's Manufacturing and Defense Industrial Base * V. Five Macro Forces Driving Risk into America's Industrial Base * VI. Ten Risk Archetypes Threatening America's Manufacturing and Defense Industrial Base * VII. A Blueprint for Action * Appendix One: Executive Order 13806 * Appendix Two: Sector Summaries * Appendix Three: Contributing U.S. Government Agencies * Appendix Four: U.S. Government Sources * Appendix Five: Industry Listening Sessions * Appendix Six: Agreements with Foreign GovernmentsTo provide for our national security, America's manufacturing and defense industrial base must be secure, robust, resilient, and ready. To ensure taxpayer dollars are frugally and wisely spent, the defense industrial base must be cost-effective, cost-efficient, highly productive, and not unduly subsidized. In the event of contingencies, the industrial base must possess sufficient surge capabilities. Above all, America's manufacturing and defense industrial base must support economic prosperity, be globally competitive, and have the capabilities and capacity to rapidly innovate and arm our military with the lethality and dominance necessary to prevail in any conflict.All facets of the manufacturing and defense industrial base are currently under threat, at a time when strategic competitors and revisionist powers appear to be growing in strength and capability.
