Kinetic studies have traditionally being extremely useful in characterizing several physical and chemical phenomena in organic, inorganic and metallic systems. It provides valuable qualitative, quantitative and kinetic information on phase transformations, solid state precipitation, crystallization, oxidation and decomposition. Unfortunately, no single reference comprehensively presents nonisothermal kinetic analysis method for the study of complex processes, determining the actual mechanism and kinetic parameters. This book provides a new method for nonisothermal kinetics and its application in heterogeneous solid state processes. In the backdrop of limitations in existing methods, the book presents a brief review of the widely used isothermal and nonisothermal kinetic analysis methods.

Many different chemical processes take place inside solids or at solid surfaces and interfaces. However, their quantitative description sometimes seems difficult to understand. This book by Professor Schmalzried, author of the eminently successful Solid State Reactions; bridges the gap between the 'physical' and 'chemical' approaches to this subject because it is written in a language which both sides understand. For the first time, a comprehensive coverage of the rapidly developing field of Solid State Kinetics is available. The topics covered in this book go far beyond diffusional transport. Homogeneous and heterogeneous solid-state reactions, phase transitions or the influence of external fields are also treated in detail. With this background, the author explains e.g. charge transport mechanisms in ionic conductors, principles of sensor technology, or oxidation processes clearly and comprehensibly. This book is a must for every solid-state chemist and an indispensable tool for academic and industrial readers alike. From reviews: 'a first-rate reference work that a must for any science library' (J. Am Chem. Soc.) 'can be recommended without restrictions ...' (Z. Phys. Chem.)

Volume is indexed by Thomson Reuters BCI (WoS). This monograph deals with a physico-chemical approach to the problem of the solid-state growth of chemical compound layers and reaction-diffusion in binary heterogeneous systems formed by two solids; as well as a solid with a liquid or a gas. It is explained why the number of compound layers growing at the interface between the original phases is usually much lower than the number of chemical compounds in the phase diagram of a given binary system. For example, of the eight intermetallic compounds which exist in the aluminium-zirconium binary system, only ZrAl3 was found to grow as a separate layer at the Al–Zr interface under isothermal conditions. The physico-chemical approach predicts that, in most cases, the number of compound layers should not exceed two; with the main factor, resulting in the appearance of additional layers, being crack formation due to thermal expansion and volume effects.

Introductory kinetics for the undergrad materials scientist Materials Kinetics Fundamentals is an accessible and interesting introduction to kinetics processes, with a focus on materials systems. Designed for the undergraduate student, this book avoids intense mathematics to present the theory and application of kinetics in a clear, reader-friendly way. Students are first introduced to the fundamental concepts of kinetics, with illustrated diagrams, examples, text boxes, and homework questions that impart a unified, intuitive understanding. Further chapters cover the application of these concepts in the context of materials science, with real-world examples including silicon processing and integrated circuit fabrication, thin-film deposition, carbon-14 dating, steel degassing, energy conversion, and more. Instructor materials including a test bank are available through the companion website, providing a complete resource for the undergraduate materials science student. At its core, kinetics deals with rates, telling us how fast something will take place – for example, how fast water will evaporate, or how fast molten silicon will solidify. This book is designed to provide students with an introduction to kinetics' underlying principles, without rigorous math to distract from understanding. Understand universally important kinetic concepts like diffusion and reaction rate Model common kinetic processes both quantitatively and qualitatively Learn the mechanisms behind important and interesting materials systems Examine the behaviors, properties, and interactions of relevant solid materials There are a large number of books on chemical kinetics, but there are far fewer that focus on materials kinetics, and virtually none that provide an accessible, introductory-level treatment of the subject. Materials Kinetics Fundamentals fills that need, with clear, detailed explanations of these universal concepts.

Introduction to Solid State Chemistry provides a strong background to the structures of solids and factors that determine this structure. The content presented will also stress transformations of solids both in physical forms and chemical composition. In so doing, topics such as phase transitions, sintering, reactions of coordination compounds, photovoltaic compounds are described, whilst kinetics and mechanisms of solid state reactions are covered in depth. There are currently few books that deal with solid state chemistry, where a considerable number instead deal with solid state physics and materials science/engineering. This book provides someone needing or wishing to learn about the chemistry of solids a comprehensive resource that describes structures of solids, the behaviour of solids under applied stresses, the types of reactions that solids undergo, and the phenomenological aspects of reactions in solids. Kinetics of reactions in solids is very seldom covered in current literature and an understanding of the mechanisms of reactions in solids is necessary for many applications. James E. House provides a balanced treatment of structure, dynamics, and behaviour of solids at a level commensurate with upper-level undergraduates or beginning graduate students who wish to obtain an introduction and overview to solid state chemistry. - Provides a?fundamental introduction and entry point to solid state chemistry, acting as a useful prerequisite for further learning in the area - Presents a balanced approach that not only emphasizes structures of solids but also provides information on reactions of solids and how they occur - Gives much-needed focus to the kinetics of reactions of solids and their mechanisms where existing literature covers little of this - Explores crucial solid state chemistry topics such as solar energy conversion, reactions of solid coordination compounds, diffusion, sintering, and other transformations of solids - Features accessible and well-written examples and case studies featuring many new and bespoke supporting illustrations, offering an excellent framework that will help students to understand reaction mechanisms

The whole of Volume 22 is devoted to the kinetics and mechanisms of the decomposition and interaction of inorganic solids, extended to include metal carboxylates. After an introductory chapter on the characteristic features of reactions in the solid phase, experimental methods of investigation of solid reactions and the measurement of reaction rates are reviewed in Chapter 2 and the theory of solid state kinetics in Chapter 3. The reactions of single substances, loosely grouped on the basis of a common anion since it is this constituent which most frequently undergoes breakdown, are discussed in Chapter 4, the sequence being effectively that of increasing anion complexity. Chapter 5 covers reactions between solids, and includes catalytic processes where one solid component remains unchanged, double compound formation and rate processes involving the interactions of more than three crystalline phases. The final chapter summarises the general conclusions drawn in the text of Chapter 2-5.

In this updated and expanded second edition, new literature has been added on contaminant fate in the soil-subsurface environment. In particular, more data on the behavior of inorganic contaminants and on engineered nanomaterials were included, the latter comprising a group of “emerging contaminants” that may reach the soil and subsurface zones. New chapters are devoted to a new perspective of contaminant geochemistry, namely irreversible changes in pristine land and subsurface systems following chemical contamination. Two chapters were added on this topic, focusing attention on the impact of chemical contaminants on the matrix and properties of both liquid and solid phases of soil and subsurface domains. Contaminant impacts on irreversible changes occurring in groundwater are discussed and their irreversible changes on the porous medium solid phase are surveyed. In contrast to the geological time scale controlling natural changes of porous media liquid and solid phases, the time scale associated with chemical pollutant induced changes is far shorter and extends over a “human lifetime scale”.
