Point Defects And Related Properties Of Ceramics

Ceramic Materials: Science and Engineering is an up-to-date treatment of ceramic science, engineering, and applications in a single, integrated text. Building on a foundation of crystal structures, phase equilibria, defects and the mechanical properties of ceramic materials, students are shown how these materials are processed for a broad diversity of applications in today's society. Concepts such as how and why ions move, how ceramics interact with light and magnetic fields, and how they respond to temperature changes are discussed in the context of their applications. References to the art and history of ceramics are included throughout the text. The text concludes with discussions of ceramics in biology and medicine, ceramics as gemstones and the role of ceramics in the interplay between industry and the environment. Extensively illustrated, the text also includes questions for the student and recommendations for additional reading. KEY FEATURES: Combines the treatment of bioceramics, furnaces, glass, optics, pores, gemstones, and point defects in a single text Provides abundant examples and illustrations relating theory to practical applications Suitable for advanced undergraduate and graduate teaching and as a reference for researchers in materials science Written by established and successful teachers and authors with experience in both research and industry

This book discusses the mechanical properties of ceramics and aims to provide both a solid background for undergraduate students, as well as serving as a text to bring practicing engineers up to date with the latest developments in this topic so they can use and apply these to their actual engineering work. Generally, ceramics are made by moistening a mixture of clays, casting it into desired shapes and then firing it to a high temperature, a process known as 'vitrification'. The relatively late development of metallurgy was contingent on the availability of ceramics and the know-how to mold them into the appropriate forms. Because of the characteristics of ceramics, they offer great advantages over metals in specific applications in which hardness, wear resistance and chemical stability at high temperatures are essential. Clearly, modern ceramics manufacturing has come a long way from the early clay-processing fabrication method, and the last two decades have seen the development of sophisticated techniques to produce a large variety of ceramic material. The chapters of this volume are ordered to help students with their laboratory experiments and guide their observations in parallel with lectures based on the current text. Thus, the first chapter is devoted to mechanical testing. A chapter of ductile and superplastic ceramic is added to emphasize their role in modern ceramics (chapter 2). These are followed by the theoretical basis of the subject. Various aspects of the mechanical properties are discussed in the following chapters, among them, strengthening mechanisms, time dependent and cyclic deformation of ceramics. Many practical illustrations are provided representing various observations encountered in actual ceramic-structures of particularly technical significance. A comprehensive list of references at the end of each chapter is included in this textbook to provide a broad basis for further studying the subject. The work also contains a unique chapter on a topic not discussed in other textbooks on ceramics concerning nanosized ceramics. This work will also be useful as a reference for materials scientists, not only to those who specialize in ceramics.

This latest volume of the annual series contains over 900 selected abstracts of research in the field of ceramics (including, for this purpose, allotropes of carbon); reported between the appearance of Retrospective IV and about June 2003 (allowing for variations in publication dates).

This twelth volume in the series includes 589 abstracts of ceramics research papers, together with original papers on other major material groups, and theory: Studies of the EPR Parameters and Local Structure of Co2+ in ZnO, Structural and Electrical Changes in BIMNVOX Oxide-Ion Conductor, Effect of Film Thickness on Some Optical Properties of Sprayed Pyrolysis Cobalt Oxide Thin Films, A Novel Experimental Approach to Compatible Carbon Nanofiber Diffusion around Circular Carbon Micro-Post Surfaces, Structural Rigidity, Percolation and Transition-Temperature Study of the Ge19Se81-xSbx System, Physical Analysis of Structural Transformation in Ge-Incorporated a-SbxSe100-x System, Study of the Glass Transition Temperature of (Se100-xBix)90Te10 Alloys, A Boost-Up Method of MEMS-Bulk-Micromachining towards C-MEMS Fabrication for Sensing and Manipulating Bioparticles, Electrical and Dielectric Properties of Te15(Se100-xBix)85 Amorphous Glassy Alloys, Low-Power Operation of Pt/Porous Si Schottky-Diode Gas-Sensor through a Reduction in its Breakdown Voltage, Surface Composition Transformation of Thin Film based on Al Grown by CBE on the (001) GaAs Surface Due to Laser Assistance, Characterization and Properties of Iron/Silica-Sand-Nanoparticle Composites, Al-Film/Si-Substrate System Nanoscratching Response Based upon Molecular Dynamics Simulation in NEMS, Probing the Activation Migration Enthalpies of Dislocations in 2024 Aircraft Material using Nuclear and Electrical Techniques, A Numerical Simulation Approach to Convection, Buoyancy Effect, Microfiltration and Flow Analysis as an Influential Lead for Designing and Dimensioning in MEMS, Prediction of Transient Temperature Distribution, HAZ Width and Microstructural Analysis of Submerged Arc-Welded Structural Steel Plates, Evaluation of the Effect of Catalyst Pore-Size Distribution on the Effectiveness Factor in Ethylbenzene Dehydrogenation by Orthogonal Collocation.

Concepts such as how and why ions move, how ceramics interact with light and magnetic fields, and how they respond to temperature changes are discussed in the context of their applications. References to the art and history of ceramics are included throughout the text, and a chapter is devoted to ceramics as gemstones. This course-tested text now includes expanded chapters on the role of ceramics in industry and their impact on the environment as well as a chapter devoted to applications of ceramic materials in clean energy technologies. Also new are expanded sets of text-specific homework problems and other resources for instructors. The revised and updated Second Edition is further enhanced with color illustrations throughout the text.
