This volume, which is unique in its coverage, provides a general introduction to the properties and nature of transition metal carbides and nitrides, and covers their latest applications in a wide variety of fields. It is directed at both experts and nonexperts in the fields of materials science, solid-state chemistry, physics, ceramics engineering and catalysis. The first chapter provides an overview, with other chapters covering theory of bonding, structure and composition, catalytic properties, physical properties, new methods of preparation, and spectroscopy and microscopy. 

In this chapter, we describe the synthesis and characterisation of the microstructure and properties of layered-graded alumina-matrix composites through liquid infiltration. This approach is relatively simple and offers excellent control over the depth of the graded layer. The presence of a graded dispersion of reinforced particles in the alumina matrix has a profound influence on the physical and mechanical properties of the composites. An overview of the infiltration kinetics and the use of the infiltration process as a new philosophy for tailoring novel graded ceramic systems are also presented. 

The aim of this chapter is to present an overview of the performance of ceramic matrix composites (CMCs) under conditions of thermal shock, i.e. when they are subjected to sudden changes in temperature during either heating or cooling.

Each chapter in the book has been written by an internationally recognized expert in the field of ceramic matrix composites. The chapters are organized to include a substantial review of the fundamentals. The authors have integrated material from a wide range of sources to provide a perspective for their own research contributions. The overview character of the chapters makes this book useful not only to researchers in the ceramics community but also to graduate students in advanced ceramics courses. 

Silicon-containing preceramic polymers are useful precursors for the preparation of ceramic powders and fibers and for ceramic binder applications (i). Ceramic fibers are increasingly important for the reinforcement of ceramic, plastic, and metal matrix composites (2, 3). This chapter will emphasize those polymer systems that have been used to prepare ceramic fibers. An overview of polymer and fiber processing, as well as polymer and fiber characterization, will be described to illustrate the current status of this field. Finally, some key issues will be presented that must be addressed if this area is to continue to advance. 

OVERVIEW OF CONTINUOUS FIBRE-REINFORCED GLASS AND GLASS-CERAMIC MATRIX COMPOSITES... 

A great variety of silicate matrices has been considered for the fabrication of fibre-reinforced glass and glass-ceramic matrix composites [4-6,29-31]. Typical matrices investigated are listed in Table 1. Table 2 gives an overview of different composite systems developed and some of the most remarkable properties achieved. 

The purpose of this chapter is to provide an overview of the chemistry, processing and application of boron-containing preceramic polymers in the BN system. The nonoxide precursor route, also called the Polymer Derived Ceramics (PDCs) route, represents a chemical approach based on the use of air- and/or moisture-sensitive (molecular or polymeric) precursors by means of standard Schlenk techniques and vacuum/argon lines. This precursor route allows the chemistry (e.g., elemental composition, compositional homogeneity and atomic architecture) of molecular precursors to be controlled and tailored in order to provide the ensuing preceramic polymers... 

This chapter is an overview of the applications for cart>on and ceramic fibers. These applications mainiy involve composite materiais where the fibers are embedded in a polymer or a metallic or ceramic matrix, depending on the service temperature or the specific properties which are required.

Chapter 4 discusses polymer matrix composites (PMCs) used in structural applications. This chapter covers PMCs used in thermal management and electronic packaging. It also provides an overview of metal matrix composites (MMCs), ceramic matrix composites (CMCs), and carbon matrix composites (CAMCs). 

There has been a long term and sustained research and development effort in advanced ceramics in China over last few decades. In this presentation, an overview of recent research and development in the area of advanced ceramics and ceramic matrix composites will be presented. Some key results from national projects funded by Ministry of Science and Technology and National Nature Scientific Foundation of China will be provided. In addition, recent results of R D activities in Shanghai Institute of Ceramics (SICCAS) especially in ceramic matrix composites, transparent ceramics, bio-ceramics, and mesoporous materials will also be presented. 

To meet the foregoing requirements, the composition of LaCrOs was modified by doping of lower valence alkaline ions, such as Ca ", Mg +, and Sr, at the La " " or sites. The substitution of La site and Cr site with the other elements can decrease the sintering temperature and increase the electronic conductivity. So far, a number of papers have been published regarding the physical and chemical properties of doped LaCrOs. The present chapter describes the overview of LaCrOs-based ceramics for SOFC interconnects. The following topics are introduced and discussed ...
