Non Stoichiometry Point Defects And Cation Tracer Diffusion In Iron Based Spinels

Structure and Concentration of Point Defects in Selected Spinels and Simple Oxides presents diagrams and numerical data of important properties of spinels and oxides based on experimental results published in the literature. The values of many parameters presented can be used for optimization of preparation of new systems, to predict the practical properties of these systems. Applications include electronic devices, new metallic alloys with improved corrosion resistance, new ceramic materials, and novel catalysts, particularly for oxygen evolution and reduction reactions. Organized into four comprehensive parts, the authors present the problem of the structure and concentration of ionic and electronic defects in magnetite and hausmannite, pure and doped with M3+ cations, and in spinels exhibiting magnetic properties and high electric conductance. Additional Features include: Includes 236 figures presenting equilibrium diagrams of point defects and other useful details related to stoichiometric and nonstoichiometric spinels and oxides. Details novel methods of calculation of equilibria involving point defects. Collects scattered data published in nearly 500 original articles since the 1950s on spinels and oxides in one useful volume. Building upon the data presented, this book is an indispensable reference for material scientists and engineers developing new metal or oxide-based systems can easily calculate other useful parameters and compare the properties of different materials to select the best candidates for an intended use.

Volume 72 of Reviews in Mineralogy and Geochemistry represents an extensive compilation of the material presented by the invited speakers at a short course on Diffusion in Minerals and Melts held prior (December 11-12, 2010) to the Annual fall meeting of the American Geophysical Union in San Francisco, California. The short course was held at the Napa Valley Marriott Hotel and Spa in Napa, California and was sponsored by the Mineralogical Society of America and the Geochemical Society.
