This chapter discusses the performance behaviour of ceramic nanocomposites under conditions of thermal shock, i.e. when they are subjected to sudden changes in temperature during either heating or cooling or may be in flame propagating zones. For example, during emergency shut-downs of gas turbines, cool air is drawn from the still spinning compressor and driven through the hot sections: the temperature at the turbine outlet decreases by more than 800°C within one second and ceramic nanocomposite materials are an

Ceramic nanocomposites have been found to have improved hardness, strength, toughness and creep resistance compared to conventional ceramic matrix composites. Ceramic nanocomposites reviews the structure and properties of these nanocomposites as well as manufacturing and applications. Part one looks at the properties of different ceramic nanocomposites, including thermal shock resistance, flame retardancy, magnetic and optical properties as well as failure mechanisms. Part two deals with the different types of ceramic nanocomposites, including the use of ceramic particles in metal matrix

This chapter covers the electrical conductivity of polymer– ceramic and ceramic–ceramic nanocomposites with a major emphasis on the ionic conductivity. These nanocomposites are potentially important materials as electrolytes for power generation and energy storage devices. The nanocomposites offer major enhancements in ionic conductivity because of an underlying basic physical mechanism emanating from their structure. The basic physical mechanism for conductivity enhancement is the space charge effect. The chapter explains applicability and quantification of the effect for lithium ion conducting

This chapter reviews the preparation and study of high-temperature superconducting (SC) nanocomposites based on SC ceramics and various polymeric binders. Regardless of the size of the ceramic grains, any increase in their quantity results in an increase of resistance to rupture and modulus and a decrease in limiting deformation, whilst a similar increase in the average ceramic grain size worsens resistance properties. Investigation of the SC, thermo-chemical, mechanical and dynamic-mechanical properties of the samples are discussed. Superconducting properties of the

Nanoscale constituents in nanocomposites possess excellent optical properties that differ from the macroscale properties. This chapter focuses on the optical properties of nanoscale materials incorporated in glass and ceramics, especially transmittance, absorption, non-linearity and luminescence. The fluorescence property of carbon nanotube–glass composite is a new observation which has hitherto not been studied. All these properties make them a potential material for optical sensors, ultraviolet–infrared shielding windows and other biological applications.

One of the most recent developments in ceramics has been the distribution of multiple phases in a ceramic composite at the nanoscopic length scale. An advanced nanocomposite microstructure such as that of polycrystalline silicon carbide (SiC)–silicon nitride (Si3N4) nanocomposites contains multiple length scales with grain boundary thickness of the order of 50nm, SiC particle sizes of the order of 200–300nm and Si3N4 grain sizes of the order of 0.8–1.5μm. Designing the microstructure of such a composite for

This chapter first builds a basic understanding of structural failure and its determining critical factors. It describes typical fracture origins and modes of crack propagation. It then deals with the concept of reinforcing ceramic nanocomposites. Different strategies for preventing failures are discussed, and the influence of microstructure and secondary nanometric phases on friction and wear properties of some ceramic nanocomposites is described.

This chapter introduces research conducted on metal matrix nanocomposites (MMNCs). The chapter reviews the material system used for MMNCs and explains the principles to choose the reinforcement for metal matrix composites. The mechanical properties of MMNCs fabricated by different processes are summarized and models used to predict and describe the effect of different strengthening mechanisms on MMNCs are introduced. Different approaches used to produce MMNCs are reviewed and categorized.

The chapter discusses several variants of mechanosyntheses for composite powder formation of metal alloy matrices with ceramic particles. The necessity of following progress in mechanochemical processes using different analytical methods is shown. Based on the results of experimental studies on Cu–Al/Al2O3 and Ni-Al/Al2O3 nanocomposite powder formation through mechanochemical synthesis, the method of transforming combustive processes to progressive ones by applying hydroxosalts instead of metal oxides as precursors of composites is described.
