Nitride Ceramics

A comprehensive overview of recent developments in the field of non-oxide ceramics with special emphasis placed on the combustion synthesis of group I-VI nitrides and oxynitrides. To ensure the widest possible perspective, the authors are experts in academia, industry, or government research, and each chapter discusses different synthetic methods and process parameters, as well as important material properties and applications. The result is invaluable reading for researchers and practitioners in the industry as well as those looking for an introduction to the field. It is equally of great interest to chemists and materials scientists as well as engineers working in the area of inorganic and solid-state chemistry, structural and functional materials, catalysis, metallurgy, and electrochemistry.

The current book consists of twenty-four chapters divided into three sections. Section I includes fourteen chapters in electric and magnetic ceramics which deal with modern specific research on dielectrics and their applications, on nanodielectrics, on piezoceramics, on glass ceramics with para-, anti- or ferro-electric active phases, of varistors ceramics and magnetic ceramics. Section II includes seven chapters in bioceramics which include review information and research results/data on biocompatibility, on medical applications of alumina, zirconia, silicon nitride, ZrO2, bioglass, apatite-wollastonite glass ceramic and b-tri-calcium phosphate. Section III includes three chapters in applications of ceramics in environmental improvement and protection, in water cleaning, in metal bearing wastes stabilization and in utilization of wastes from ceramic industry in concrete and concrete products.

This new handbook will be an essential resource for ceramicists. It includes contributions from leading researchers around the world and includes sections on Basic Science of Advanced Ceramics, Functional Ceramics (electro-ceramics and optoelectro-ceramics) and engineering ceramics. Contributions from more than 50 leading researchers from around the world Covers basic science of advanced ceramics, functional ceramics (electro-ceramics and optoelectro-ceramics), and engineering ceramics Approximately 750 illustrations

This proceedings includes papers presented at the Innovative Processing and Synthesis of Ceramics, Glasses and Composites symposium. Topics include powders, films, coatings, fibers, composites, and functionally graded materials; sol-gel, polymer precursor, and soft chemistry techniques; novel processing and microstructure-property relationships; reaction forming, combustion synthesis, and CVD; oxidation of metals and mechanical alloying; electrophoresis and plasma processing; and mechanism and kinetics of processes.

The suggestion that a NATO Advanced Study Institute would be an excellent forum for reviews and informed discussion on the broad subject of Nitrogen Ceramics, arose out of discussions with colleagues in the Department of Ceramics at the University of Leeds early in 1975. There was no doubt that such a meeting would be both very valuable and timely. Scientific and technological interest in the nitride ceramics and in silicon nitride in part icular had been growing steadily during the 20-year period following 1955. The intensive five-year programme initiated by the Advanced Research Projects Agency of the U. S. Department of Defence, on the development of a design capability in brittle materials for high temperature applications, had been based principally on silicon nitride and silicon carbide ceramics, and was due to reach the end of its first stage in the autumn of 1976. It was clear that by then a considerable volume of information covering many aspects of silicon nitride would be available for presentation or review. Coincidentally, the same five-year period had seen the discovery, and increasingly detailed investigation, of ceramic materials based on the AI-Si-N-O and similar systems. Besides being of great interest for their crystal chemistry and structural relationships, some of these materials could be assumed potentially to be of equal importance to the silicon nitride ceramics. More recently progress had also been made in the sintering of covalent materials, as demonstrated for the case of silicon carbide.

It has been three decades since the last significant book was published on SiC ceramics (other than those books that specifically focus on SiC semiconductors). Thirty years has been a long time in the world of SiC ceramics. In the early 1990s, SiC was still a relatively obscure ceramic even within the materials community, prominent only as an industrial abrasive (carborundum), and a refractory (Chapter 7). This has all changed dramatically in the 21st century. For example, As a semiconductor, SiC greatly surpasses silicon in performance, especially in high-power systems. Its market penetration since its launch in 2001 has been exponential. Single-crystal SiC semiconductors are covered in Chapter 3 Millions of military and paramilitary personnel have globally been protected with lightweight SiC body armour, since the late 1990s. Body armour is covered in Chapters 4 and 5 SiC–SiC is a composite material close to commercialization that makes possible high-temperature load-bearing applications hitherto only able to be hypothesized: from ultra-high-temperature jet turbine blades to advanced nuclear fuel encapsulation, the possibilities are very promising. Aerospace applications are covered in Chapter 9 Other key areas that are addressed are blast-resistant SiC vehicle/vessel armour in Chapter 8 and wear-resistant SiC ceramics in Chapter 6 Silicon Carbide Ceramics will be an essential reference resource for academic and industrial researchers and materials scientists and engineers working in ceramic materials for the semiconductor, defence, aerospace, wear resistance and refractory fields Presents an extensive review of the history, production and properties of SiC ceramics, including their characterization and applications Discusses classical and state-of-the-art sintering technologies for SiC ceramics Focuses on the future of ceramic manufacturing and advanced ceramic additive technologies
