Book Description
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.

Book Description
Written by a leading practitioner and teacher in the field of ceramic science and engineering, this outstanding text provides advanced undergraduate- and graduate-level students with a comprehensive, up-to-date Introduction to Phase Equilibria in Ceramic Systems. Building upon a concise definition of the phase rule, the book logically proceeds from one- and two-component systems through increasingly complex systems, enabling students to utilize the phase rule in real applications. Unique because of its emphasis on phase diagrams, timely because of the rising importance of ceramic applications, practical because of its pedagogical approach, Introduction to Phase Equilibria in Ceramic Systems offers end-of-chapter review problems, extensive reading lists, a solid thermodynamic foundation and clear perspectives on the special properties of ceramics as compared to metals.This authoritative volume fills a broad gap in the literature, helping undergraduate- and graduate-level students of ceramic engineering and materials science to approach this demanding subject in a rational, confident fashion. In addition, Introduction to Phase Equilibria in Ceramic Systems serves as a valuable supplement to undergraduate-level metallurgy programs.

Book Description
The investigation of multi-component complex systems composed of oxides, nitrides, and carbides has intensified in the last few years. Phase Diagrams in Advanced Ceramics reviews some of the recent advances inthe understanding of these composite systems, providing insight into how phase diagrams can be utilized in the fabrication of whiskers and ceramic-matrix whisker-reinforced ceramics. Phase relations and sintering information is reviewed for transparent polycrystalline oxides. Phase diagrams are discussed to predict alkali oxide corrosion of alumino-silicate references. - Understanding the development, manufacture, and use of complex, multi-component ceramic materials composed of silicon nitride-metal oxides-nitride-carbide systems - Development and use of whisker and whisker-reinforced ceramics composed of materials such as alumina, silicon-nitride, silicon carbide, and directly solidified eutectic ceramics - Application of phase diagrams to the production of advanced composites such as alumina-matrix, zirconium diboride and titanium, hafnium, zirconium, carbides, and borides - Phase chemistry in the development of transparent poly-crystal and oxides, including yttria, alumina, and magnesium aluminate - Improvements concerning the knowledge of complex multi-component materials composed of oxides, nitrides, and carbides, and knowledge of how to fabricate composite materials containing whiskers and ceramic hosts - New developments in making transparent ceramic materials

Book Description
Phase Diagrams: Materials Science and Technology, Volume V is a six-chapter text that covers the use of phase diagrams in the understanding and development of inorganic materials. This volume first examines the atomistic understanding of the geometry of phase diagrams and the thermodynamic parameters on which the diagrams are based, as well as the relations of diagrams to crystal chemistry. The topics are followed by discussions on the most important thermodynamic theories of nonstoichiometry in binary oxide systems and the theories of spinodal decomposition that are relevant to crystalline nonmetals, especially to mixed crystalline oxides. Other chapters explore the phase equilibrium relations of phosphatic apatites including fluor-, chlor-, and hydroxyanion-containing compounds and of sialons and other nitrogen ceramics. The last chapter describes the mechanical, chemical, and thermal shock-resistant properties required of materials for stringent application. This chapter highlights the maximizing of the thermal shock resistance of silicate ceramics through lowering thermal expansion to meet the required properties of this application. The use of phase diagrams in the development of low thermal expansion materials for these applications is also discussed. This book will be useful to all scientists, engineers, and materials science students who are investigating and developing materials, as well as to the end user of the materials.

Book Description
Phase diagrams are "maps" materials scientists often use to design new materials. They define what compounds and solutions are formed and their respective compositions and amounts when several elements are mixed together under a certain temperature and pressure. This monograph is the most comprehensive reference book on experimental methods for phase diagram determination. It covers a wide range of methods that have been used to determine phase diagrams of metals, ceramics, slags, and hydrides.* Extensive discussion on methodologies of experimental measurements and data assessments * Written by experts around the world, covering both traditional and combinatorial methodologies* A must-read for experimental measurements of phase diagrams

Book Description
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.

Book Description
High-temperature ceramic fibers are the key components of ceramic matrix composites (CMCs). Ceramic fiber properties (strength, temperature and creep resistance, for example)-along with the debonding characteristics of their coatings-determine the properties of CMCs. This report outlines the state of the art in high-temperature ceramic fibers and coatings, assesses fibers and coatings in terms of future needs, and recommends promising avenues of research. CMCs are also discussed in this report to provide a context for discussing high-temperature ceramic fibers and coatings.
