Ceramic Powders For High Tech Applications

The book consists of papers on several methods used in the preparation of basic ceramic powders with the required particle size distribution and purity. Processing methods such as spray drying, thermal decomposition of organometallic complexes, the sol-gel process and solution sythesis, among others, have been discussed.

High-tech ceramics pose many challenges to the scientist and engineer because of their demanding production and processing requirements. Leading experts in the field address these problems not only from a fundamental scientific point of view but with particular reference to a broad range of engineering applications. This edited volume is based on invited talks given at a symposium held at the ETH Zurich in November, 1988, sponsored by the International Latsis Foundation of Geneva.

This volume constitutes the Proceedings of the November 8-10, 1982 Conference on EMERGENT PROCESS METHODS FOR HIGH TECHNOLOGY CERAMICS, held at North Carolina State University in Raleigh. It was the nineteenth in a series of "University Conferences on Ceramic Sci ence" initiated in 1964 by four institutions of which North Carolina State University is a charter member, along with the University of California at Berkeley, Notre Dame University, and the New York State College of Ceramics at Alfred University. More recently, ceramic oriented faculty in departments at the Pennsylvania State University and Case-Western Reserve University have joined the four initial institutions as permanent members of the consortium. These research oriented conferences, each uniquely concerned with a timely ceramic theme, have been well attended by audiences which typically were both international and interdisciplinary in character; their published Proceedings have been well received and are frequently cited. This three day conference addressed the fundamental scientific background as well as the technological state-of-the-art of several novel methods which are beginning to influence present and future directions for non-traditional ceramic processing, thus affecting many of the advanced ceramic materials needed for a wide variety of research and industrial applications. The number, the importance and the application of new ceramic processing techniques have expanded considerably during the last ten years.

This collection emphasizes the advances of powder and ceramic/glass materials in the fundamental research, technology development, and industrial applications. Ceramic materials science covers the science and technology of creating objects from inorganic, non-metallic materials, and includes design, synthesis, and fabrication of ceramics, glasses, advanced concretes, and ceramic-metal composites. In recent years, the hybrids of ceramic and metallic materials have received plenty of interdisciplinary inspirations and achievements in material processes and functional applications including ionic conductors, catalysis, energy conversion and storage, superconductors, semiconductor, filtrations, etc. Topics cover, but are not limited to:· Silicates, oxides, and non-oxide ceramics and glasses · Synthesis, characterization, modeling, and simulation of ceramic materials · Design and control of ceramic microstructure and properties · Ceramic powders and processing · Catalyst and catalyst support materials · Fundamental understanding of ceramic materials and processes · Novel methods, techniques, and instruments used to characterize ceramics and glasses · High entropy ceramics (and/or entropy stabilized, complex-concentrated, compositionally-complex, multi-principal cation ceramics) · Bioceramics, electronic, magnetic ceramics, and applications · Surface treatment and ceramic thin films, membranes, and coatings · Porous ceramic materials · Hybrid systems of ceramic, metal, and/or polymer composites · Ceramics used for extreme environments · Metallurgical byproducts for ceramic manufacturing

Ceramic powder synthesis and processing are two of the most important technologies in chemical engineering and the ceramics-related area of materials science. This book covers both the processing and the synthesis ofceramic powders in great depth and is indeed the only up-to-date, comprehensive source on the subject available.The application of modern scientific and engineering methods to the field of ceramic powder synthesis has resulted in much greater control of properties. Fundamentals of Ceramic Powder Processing and Synthesis presents examples of these modern methods as they apply to ceramic powders. The book is organized to describe the natural and synthetic raw materials that comprise contemporary ceramics. It covers the three reactant processes used in synthetic ceramic powder synthesis: solid, liquid, andgas.Ceramic powder processing, as a field of materials processing, is undergoing rapid expansion. The present volume is intended as a complete and useful source on this subject of great current interest. It provides comprehensive coverage from a strong chemistry and chemical engineering perspective and is especially applicable to materials scientists, chemical engineers, and applied chemists. Key Features* The most complete and updated reference source on the subject* Comprehensive coverage from a stron chemical engineering and chemistry perspective* Emphasis on both natural and synthetic raw materials in ceramic powder synthesis* Information on reaction kinetics* Superior, more comprehensive coverage than that in existing texts* Sample problems and exercises* Problems at the end of each chapter which supplement the material

This edition of the Progress in Ceramic Technology series is a select compilation of articles on nanotechnology applications and markets previously published in ACerS publications, including The American Ceramic Society Bulletin, Journal of the American Ceramic Society, International Journal of Applied Ceramic Technology, Ceramic Engineering and Science Proceedings (CESP) and Ceramic Transactions (CT). The American Ceramic Society contributes to the progress of nanotechnology by providing forums for information exchange during its various meetings and by publishing articles in its various journals and proceedings.

The current book contains twenty-two chapters and is divided into three sections. Section I consists of nine chapters which discuss synthesis through innovative as well as modified conventional techniques of certain advanced ceramics (e.g. target materials, high strength porous ceramics, optical and thermo-luminescent ceramics, ceramic powders and fibers) and their characterization using a combination of well known and advanced techniques. Section II is also composed of nine chapters, which are dealing with the aqueous processing of nitride ceramics, the shape and size optimization of ceramic components through design methodologies and manufacturing technologies, the sinterability and properties of ZnNb oxide ceramics, the grinding optimization, the redox behaviour of ceria based and related materials, the alloy reinforcement by ceramic particles addition, the sintering study through dihedral surface angle using AFM and the surface modification and properties induced by a laser beam in pressings of ceramic powders. Section III includes four chapters which are dealing with the deposition of ceramic powders for oxide fuel cells preparation, the perovskite type ceramics for solid fuel cells, the ceramics for laser applications and fabrication and the characterization and modeling of protonic ceramics.

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.
