Spinel Materials reviews the key principles, methods, applications, and research directions of spinel materials. Fundamental aspects such as the relationship between their size, metal ion occupancy, and physical behavior are introduced. Then, synthesis methods to produce these materials and characterization methods used to observe their behaviors are reviewed. The electronic, optical and magnetic properties of spinel materials make them suitable for wide range of uses, but especially for energy applications. The book reviews the most relevant opportunities and challenges of the use of spinel materials for energy applications. Spinel Materials is suitable for researchers and practitioners working in the subject area of materials science and engineering and may also be interest to those working in chemistry or physics disciplines. Reviews basic principles of spinel materials, including their structure and magnetic, dielectric, electrical, and optical behavior Provides an overview of synthesis methods to produce spinel materials Discusses the applications of spinels for energy and environmental remediation
