Sol-Gel Science: The Physics and Chemistry of Sol-Gel Processing presents the physical and chemical principles of the sol-gel process. The book emphasizes the science behind sol-gel processing with a chapter devoted to applications. The first chapter introduces basic terminology, provides a brief historical sketch, and identifies some excellent texts for background reading. Chapters 2 and 3 discuss the mechanisms of hydrolysis and condensation for nonsilicate and silicate systems. Chapter 4 deals with stabilization and gelation of sols. Chapter 5 reviews theories of gelation and examines the predicted and observed changes in the properties of a sol in the vicinity of the gel point. Chapter 6 describes the changes in structure and properties that occur during aging of a gel in its pore liquor (or some other liquid). The discussion of drying is divided into two parts, with the theory concentrated in Chapter 7 and the phenomenology in Chapter 8. The structure of dried gels is explored in Chapter 9. Chapter 10 shows the possibility of using the gel as a substrate for chemical reactions or of modifying the bulk composition of the resulting ceramic by performing a surface reaction (such as nitridation) on the gel. Chapter 11 reviews the theory and practice of sintering, describing the mechanisms that govern densification of amorphous and crystalline materials, and showing the advantages of avoiding crystallization before sintering is complete. The properties of gel-derived and conventional ceramics are discussed in Chapter 12. The preparation of films is such an important aspect of sol-gel technology that the fundamentals of film formation are treated at length in Chapter 13. Films and other applications are briefly reviewed in Chapter 14. Materials scientists and researchers in the field of sol-gel processing will find the book invaluable.

Many believe that the silicon/information age is heading to the Age of Biology and that the next frontier in ceramics will most likely require molecular level or nanoscale control. What, then, is the role of ceramics in the age of biology? As we change from an energy-rich society to an energy-declining society, how can ceramic materials appease the problem? This new edition of Chemical Processing of Ceramics offers a scientific and technological framework for achieving creative solutions to these questions. Edited by experts and containing chapters by leading researchers in the field, the book uses an interdisciplinary approach to cover topics ranging from starting materials to device applications. The book begins with a discussion of starting material, highlighting how to prepare and modify them in the nanoscale range. The chapter authors discuss the synthesis, characterization, and behavior of ceramic powders, the processing of ceramic films via sol-gel technique, and the fabrication of nonoxide ceramics. They also present coverage of several specific thin films, membranes, ferroelectrics, bioceramics, dieletrics, batteries, and superconductors. Although the book is edited, it is organized to reflect the chemical sequence of ceramic processing and the coherent theme of chemical processing for advanced ceramic materials. The coverage of molecular/nanoprocessing techniques that result in new materials will enable researchers and engineers to meet the challenge of producing inorganic materials for use in the applications of the future.

Emphasizes the importance of surface and colloid chemistry in the manufacture of high-performance ceramics. Examines processing-property relationships, powderproductionandcharacte6zation,the dispersion properties of powders in liquids, the rheology of concentrated suspensions, and the surface and colloid chemistry aspects of the most widely used forming methods.

Although ceramics have been known to mankind literally for millennia, research has never ceased. Apart from the classic uses as a bulk material in pottery, construction, and decoration, the latter half of the twentieth century saw an explosive growth of application fields, such as electrical and thermal insulators, wear-resistant bearings, surface coatings, lightweight armour, or aerospace materials. In addition to plain, hard solids, modern ceramics come in many new guises such as fabrics, ultrathin films, microstructures and hybrid composites. Built on the solid foundations laid down by the 20-volume series Materials Science and Technology, Ceramics Science and Technology picks out this exciting material class and illuminates it from all sides. Materials scientists, engineers, chemists, biochemists, physicists and medical researchers alike will find this work a treasure trove for a wide range of ceramics knowledge from theory and fundamentals to practical approaches and problem solutions.

Examines the latest processing and fabrication methods There is increasing interest in the application of advanced ceramic materials in diverse areas such as transportation, energy, environmental protection and remediation, communications, health, and aerospace. This book guides readers through a broad selection of key processing techniques for ceramics and their composites, enabling them to manufacture ceramic products and components with the properties needed for various industrial applications. With chapters contributed by internationally recognized experts in the field of ceramics, the book includes traditional fabrication routes as well as new and emerging approaches in order to meet the increasing demand for more reliable ceramic materials. Ceramics and Composites Processing Methods is divided into three sections: * Densification, covering the fundamentals and practice of sintering, pulsed electric current sintering, and viscous phase silicate processing * Chemical Methods, examining colloidal methods, sol-gel, gel casting, polymer processing, chemical vapor deposition, chemical vapor infiltration, reactive melt infiltration, and combustion synthesis * Physical Methods, including directional solidification, solid free-form fabrication, microwave processing, electrophoretic deposition, and plasma spraying Each chapter focuses on a particular processing method or approach. Collectively, these chapters offer readers comprehensive, state-of-the-science information on the many approaches, techniques, and methods for the processing and fabrication of advanced ceramics and ceramic composites. With its coverage of the latest processing methods, Ceramics and Composites Processing Methods is recommended for researchers and students in ceramics, materials science, structural materials, biomedical engineering, and nanotechnology.

Organic Additives and Ceramic Processing: With Applications in Powder Metallurgy, Ink, and Paint describes the major manufacturing processes, such as slip casting, tape casting, injection molding, etc. The book covers each subject, including the ceramic processes, organic chemical structures, polymers, colloid science and others, starting from fundamental principles, with many literature references for further reading. After the fundamentals, detailed case studies from industrial applications are described for the optimization of solvents, dispersants, binders, plasticizers, lubricants and some minor additives. A wide range of information is covered, beginning with fundamental equations for students, and extending to advanced applications for development workers and factory problem solvers. Shanefield undertook this ambitious task only because of the previous lack of resources that address the growing need for detailed information on organic additives for ceramics. Suitable for use as a textbook and as a reference source for working ceramists and chemists who wish to supply the ceramics industry with additives.
