Rare Earths

The Rare Earths: Their Occurrence, Chemistry, and Technology is a comprehensive scientific treatise authored by F. H. Spedding and A. H. Daane, first published in 1948. This seminal work delves deeply into the fascinating world of rare earth elements, offering an authoritative exploration of their natural occurrence, chemical properties, and technological applications. The book begins with a historical overview, tracing the discovery and early study of rare earths, and then systematically examines the mineralogical sources and geographical distribution of these elements. Detailed chapters are devoted to the complex chemistry of rare earths, including their atomic structure, methods of separation, and the unique challenges posed by their similar chemical behaviors. The authors provide an in-depth analysis of the extraction and purification processes, discussing both traditional and modern techniques, and highlighting the advances that have enabled the isolation of individual rare earth elements. The book also explores the physical and chemical properties of each rare earth, including their compounds and alloys, and discusses their roles in various industrial and technological fields, such as metallurgy, electronics, and catalysis. With numerous tables, diagrams, and references, The Rare Earths: Their Occurrence, Chemistry, and Technology serves as an invaluable resource for chemists, mineralogists, engineers, and students interested in the science and technology of these strategically important elements.
