Recent developments in advanced ceramics are critically evaluated in respect to their thermal shock and thermal fatigue behavior from an interdisciplinary viewpoint by leading experts. The book covers the aspects of material development, mechanical and fracture mechanical models and experimental testing methods. Special emphasis is given to the influence of a rising crack resistance on the thermal shock behavior, novel irradiation testing methods for a quantitative characterization of the thermal shock and fatigue loading as well as detailed fracture mechanical models for single and multiple crack propagation. This book summarizes developments of the last decade concerning the thermal shock and thermal fatigue behavior of advanced ceramics. The scientific articles of the book were carefully arranged in order to achieve a textbook-like form which will be of great value to researchers and students.

We have evaluated the microstructural/mechanical, and thermal shock/fatigue behavior and have conducted stress analyses of hot-gas candle filters made by various manufacturers. These filters include both monolithic and composite ceramics. Mechanical-property measurement of the composite filters included diametral compression testing with O-ring specimens and burst testing of short filter segments using rubber plug. In general, strength values obtained by burst testing were lower than those obtained by O-ring compression testing. During single-cycle thermal-shock tests, the composite filters showed little or no strength degradation when quenched from temperatures between 900 and 1000°C. At higher quenching temperatures, slow strength degradation was observed. The monolithic SiC filters showed no strength degradation when quenched from temperatures of up to (almost equal to)700-900°C, but displayed decreased strength at a relatively sharp rate when quenched from higher temperatures. On the other hand, a recrystallized monolithic SiC filter showed higher initial strength and retained this strength to higher quenching temperatures than did regular SiC filters. This may be related to the difference in strength of grain boundary phases in the two cases. In thermal cycles between room temperature and 800- 1000°C, both monolithic and composite filters show a small strength degradation up to three cycles, beyond which the strength remained unchanged. Results of rubber-plug burst testing on composite filters were analyzed to determine the anisotropic elastic constants of the composite in the hoop direction. When these results are combined with axial elastic constants determined from axial tensile tests, the composite can be analyzed for stress due to mechanical (e. g., internal pressure) or thermal loading (thermal shock during pulse cleaning). The stresses can be compared with the strength of the composite to predict filter performance.

The advent of engineering-designed polymer matrix composites in the late 1940s has provided an impetus for the emergence of sophisticated ceramic matrix composites. The development of CMCs is a promising means of achieving lightweight, structural materials combining high temperature strength with improved fracture toughness, damage tolerance and thermal shock resistance. Considerable research effort is being expended in the optimisation of ceramic matrix composite systems, with particular emphasis being placed on the establishment of reliable and cost-effective fabrication procedures. Ceramic matrix composites consists of a collection of chapters reviewing and describing the latest advances, challenges and future trends in the microstructure and property relationship of five areas of CMCs. Part one focuses on fibre, whisker and particulate-reinforced ceramic matrix composites, part two explores graded and layered ceramics, while the five chapters in part three cover nanostructured CMCs in some detail. Refractory and speciality ceramic composites are looked at in part four, with chapters on magnesia-spinel composite refractory materials, thermal shock of CMCs and superplastic CMCs. Finally, part four is dedicated to non-oxide ceramic composites. Ceramic matrix composites is a comprehensive evaluation of all aspects of the interdependence of processing, microstructure, properties and performance of each of the five categories of CMC, with chapters from experienced and established researchers. It will be essential for researchers and engineers in the field of ceramics and more widely, in the field of inorganic materials. Looks at the latest advances, challenges and future trends Compiled by experienced and established researchers in the field Essential for researchers and engineers

Corrosion behaviour is one of the most poorly understood characteristics of ceramics. A balanced mixture of scientists from material science, metallurgy, physics, chemistry and mineralogy sum up the state of the art of measurement and modelling and reveal future research directions. The book reviews the theory of corrosion of ceramics, including the diffusion of gases and the predictions of thermodynamics; it discusses critically the kinetic models and representation tools for layer growths and material destruction. Corrosion of nitrides, carbides and oxides by simple and complex gases (O2, H2O, SO2, halides) and melts (ionic and metallic) reveal current measurement and modelling methods, advanced experimental techniques, such as laser diagnostics, TV holography, Raman spectroscopy and NDE surface methods. Frontier areas (e.g. the modelling of porous materials corrosion and protection) are revealed. For scientists and engineers in materials science, dealing with ceramics and their application. A valuable source for research students, solid state physicists and physical chemists.
