Spinel Materials: Synthesis, Characterization, and Applications 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, the 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. This resource is suitable for researchers and practitioners working in the subject area of materials science and engineering, and may also be of interest to those working in chemistry or physics disciplines.
