Nonstoichiometric Oxides by O.T. Soerensen Pdf

Nonstoichiometric Oxides discusses the thermodynamic and structural studies of nonstoichiometric oxides. This eight-chapter text also covers the defect-defect interactions in these compounds. The introductory chapters describe the thermodynamic properties of nonstoichiometric oxides in terms of defect complexes using the classical thermodynamic principles and from a statistical thermodynamics point of view. These chapters also include statistical thermodynamic models that indicate the ordered nonstoichiometric phase range in these oxides. The subsequent chapters examine the transport properties, such as diffusion and electrical conductivity. Diffusion theories and experimental diffusion coefficients for several systems, as well as the electrical properties of the highly defective ionic and mixed oxide conductor, are specifically tackled in these chapters. The concluding chapters present the pertinent results obtained in nonstoichiometric oxide structural studies using high-resolution electron microscopy and X-ray and neutron diffraction. Inorganic chemists and inorganic chemistry teachers and students will greatly appreciate this book.

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.

The Aqueous Chemistry of Oxides by Bruce C. Bunker,William Howard Casey Pdf

Our planet is largely composed of oxides. Almost every material that we humans encounter or use is derived from the oxide building blocks that comprise the Earth's crust. Water is by far the most abundant and useful liquid on the planet. Chemical reactions between water and oxides are the most prevalent reactions on the surface of the earth. Throughout history, people have exploited oxide-water reactions to build shelters, make tools, and in modern times develop some of our most advanced technologies. The Aqueous Chemistry of Oxides represents the first single-volume text that encapsulates all of the critical issues associated with how oxide materials interact with aqueous solutions. It serves as a central reference for scientific disciplines, including chemistry, geology, materials science, and environmental science. The text is organized to encompass the chemical properties of oxides, oxide synthesis in water, technological reactions, and oxide-water reactions in all of the Earth's major environments. The book highlights a wide range of scientific literature in a central location, allowing readers and scholars to access a broad range of specialized research topics.

Methane Combustion over Lanthanum-based Perovskite Mixed Oxides by Hamidreza Arandiyan Pdf

This book presents current research into the catalytic combustion of methane using perovskite-type oxides (ABO3). Catalytic combustion has been developed as a method of promoting efficient combustion with minimum pollutant formation as compared to conventional catalytic combustion. Recent theoretical and experimental studies have recommended that noble metals supported on (ABO3) with well-ordered porous networks show promising redox properties. Three-dimensionally ordered macroporous (3DOM) materials with interpenetrated and regular mesoporous systems have recently triggered enormous research activity due to their high surface areas, large pore volumes, uniform pore sizes, low cost, environmental benignity, and good chemical stability. These are all highly relevant in terms of the utilization of natural gas in light of recent catalytic innovations and technological advances. The book is of interest to all researchers active in utilization of natural gas with novel catalysts. The research covered comes from the most important industries and research centers in the field. The book serves not only as a text for researcher into catalytic combustion of methane, 3DOM perovskite mixed oxide, but also explores the field of green technologies by experts in academia and industry. This book will appeal to those interested in research on the environmental impact of combustion, materials and catalysis.

Non-Stoichiometric Compounds by J. Nowotny,W. Weppner Pdf

The material in this book is based on invited and contributed pa pers presented at the NATO Advanced Research Workshop on INon-stoichio l metric Compounds held in Ringberg Castle, Rottach-Egern (Bavarian Alps), Germany, July 3-9, 1988. The workshop followed previous meetings held in Mogilany, Poland (1980), Alenya, France (1982), Penn State, USA (1984) and Keele University, UK (1986). The aim of these workshops is to present and discuss up-to-date knowledge in the study of non-stoichiometry and its effect on materials properties as well as to indicate the most urgent research pathways required in this field. Since the subject of non-stoichiometry is interdisciplinary, the workshops bring together solid state physicists and chemists, surface scientists, materials scientists, ceramists and metallurgists. The present workshop, which gathered 42 scientists of an inter national reputation, mainly considered the effect of surfaces, grain boundaries and structural defects on materials properties. From discus sions during this meeting it emerged that correct understanding of properties of ceramic materials requires urgent studies on the defect structure of the interface region. Progress in this direction requires the development of the interface defect chemistry. This is the task for materials scientists in the near future. The present proceedings includes both theoretical and experimen tal work on general aspects of non-stoichiometry, defect structure and diffusion in relation to the bulk and to the interface region of such materials as high tech ceramics, solid electrolytes, electronic cera mics, nuclear materials and high Tc oxide superconductors.
