Available in PDF, EPUB and Kindle. Book excerpt: Microstructure characterization of advanced ceramics involves qualitative and quantitative analysis of surface topography, porosity, crystal defects, and interfaces. The structure of the surface controls interaction of ceramics with its surroundings, such as adhesion, gas adsorption, and electron exchange, which play an important role in determining overall properties of a material. Pores in ceramic materials originate from incomplete densification during the sintering process. Their presence interferes with functional properties such as mechanical strength, optical transparency, electrical conductivity, and dielectric response. Crystal defects mostly form either as a result of imperfections during the crystal growth process or as a consequence of structural phase transitions. They generally affect most functional properties of materials. So-called extended defects are interfaces that are boundaries between two solids. The most widespread tools for characterization of ceramic microstructures are microscopic techniques involving optical microscopy, different types of electron microscopy, and various scanning-probe methods. This chapter gives a brief introduction of the features of ceramic microstructure and the corresponding techniques for characterizing them.

This book was released on 2013-04-17 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ceramic products are fabricated from selected and consolidated raw materials through the application of thermal and mechanical energy. The complex connec tions between thermodynamics, chemical equilibria, fabrication processes, phase development, and ceramic properties define the undergraduate curriculum in Ceramic Science and Ceramic Engineering. Phase diagrams are usually introduced into the engineering curriculum during the study of physical chemistry, prior to specialization into ceramic engineering. This creates an artificial separation between consideration of the equilibrium description of the chemically heterogeneous system and the engineering and physical processes required for phase, microstructure, and property development in ceramic materials. Although convenient for instructional purposes, the separa tion of these topics limits the effective application of phase diagram information by the ceramic engineer in research and manufacturing problem solving. The nature of oxide phases, which define their useful engineering properties, are seldom linked to the stability of those phases which underlies their reliability as engineered products. Similarly, ceramic fabrication processes are seldom dis cussed within the context of the equilibrium or metastable phase diagram. In this text, phase diagrams are presented with a discussion of ceramics' properties and processing. Particular emphasis is placed on the nature of the oxides themselves-their structural and dielectric properties-which results in unique and stable product performance. Any set of systematic property measurements can be the basis for a phase diagram: every experiment is an experiment in the approach to phase equilibrium.

Available in PDF, EPUB and Kindle. Book excerpt: Ceramic Materials: Science and Engineering is an up-to-date treatment of ceramic science, engineering, and applications in a single, comprehensive 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 wide 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, 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.

This book was released on 2010-10-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contributions from three Focused Sessions that were part of the 34th International Conference on Advanced Ceramics and Composites (ICACC), in Daytona Beach, FL, January 24-29, 2010 are presented in this volume. The broad range of topics is captured by the Focused Session titles, which are listed as follows: FS1 - Geopolymers and other Inorganic Polymers; FS3 - Computational Design, Modeling Simulation and Characterization of Ceramics and Composites; and FS4 - Nanolaminated Ternary Carbides and Nitrides (MAX Phases). The session on Geopolymers and other Inorganic Polymers continues to attract growing attention from international researchers (USA, Australia, France, Germany, Italy, Czech Republic, and Viet Nam) and it is encouraging to see the variety of established and new applications being found for these novel and potentially useful materials. The session organizer gratefully acknowledges the support of the US Air Force Office of Scientific Research (AFOSR) through Dr. Joan Fuller. The AFOSR has continuously supported these conferences since the first meeting in Nashville, TN in 2003. Focused Session 3 was dedicated to design, modeling, simulation and characterization of ceramics and composites. 27 technical papers were presented on prediction of crystal structure and phase stability, characterization of interfaces and grain boundaries at atomic scale, optimization of electrical, optical and mechanical properties, modeling of defects and related properties, design of materials and components at different length scales, application of novel computational methods for processing. Four of these papers are included in this issue of CESP. Focused Session 4 was dedicated to MAX phases - a class of ternary carbides and nitrides with nanolaminated structure and general formula Mn+1AXn (where M is an early transition metal, A is an A-group element from IIIA to VIA, X is either C or N, and n=1, 2, 3 …). The MAX phases have attracted recently a lot of attention because they possess unique combination of metallic- and ceramic-like properties. In all, 30 technical papers were presented during this session. Four of these papers are included in this issue.

Book excerpt: Modern ceramic materials differ from the traditional materials which were only based on natural substances. It is now possible to prepare ceramics using a wide range of properties and as an area this field has evolved as a very broad scientific and technical field in its own right. In practice one encounters ceramics in practically all branches of materials science and the characteristics are so wide ranging that the common basis of these substances is not always immediately apparent. All ceramic materials are prepared by ceramic technology, and powder substances are used as the initial raw materials. Their physical properties are an expression not only of their composition, but primarily of their structure. Thus in order to fully understand the properties of ceramics, a knowledge of their structure is essential. This book is intended as a source of such knowledge. All the chapters are written by authors with vast experience in the various fields of ceramics who provide a detailed description of the interrelationships between the structure and behaviour of ceramic materials.
