Ceramic nanocomposites by N. Garmendia,B. Olalde,I. Obieta Pdf
Bioceramics and bioceramic composites have been widely used for biomedical applications for the last 50 years. This chapter discusses the advantages of using ceramic nanocomposites. The application of both inert and bioactive ceramics for orthopaedic and dental implants, as well as in the novel field of tissue engineering, is discussed and future trends are presented.
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 appropriate choice for such application. Furthermore, such a situation may arise about 100 times during the lifetime of a modern gas turbine engine. Similarly, in the nuclear industries, apart from the moderate shocks inflicted during start-up and shut-down of the system, the plasma-facing material can suffer rapid heating due to plasma discharge. Thus, when a body is subjected to a rapid temperature change such that non-linear temperature gradients appear, stresses arise due to the differential expansion of each volume element at a different temperature. The design principles for the fabrication of high-performance thermal shock resistant ceramic nanocomposites with improved mechanical properties are highlighted in this chapter. Moreover, the pertinent factors such as interface characteristics, densification methods, superplasticity and the role of nano-size particulate dispersion, which are responsible for the development of thermal shock resistant and flame retardant nanoceramic materials, are addressed and reviewed. Various test methods for the characterisation and evaluation of ceramic nanocomposites are described. Finally, the new concept of materials design for future structural ceramic nanocomposites is discussed for safe applications in high-temperature thermal shock zones.

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 nanocomposites. The applicability of the effect can be extended to other lithium ion and oxygen ion conductors. Uses of nanocomposites in energy storage and power generation devices are also covered.
Ceramic nanocomposites by A.O. Tonoyan,S.P. Davtyan Pdf
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 polymer–ceramic nanocomposites are explained by intercalation of macromolecule fragments into the interstitial layer of the ceramic grains, a phenomenon that leads to a change in the morphological structure of SC nanocomposites.
Ceramic nanocomposites by R. Banerjee,J. Mukherjee Pdf
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.
Ceramic nanocomposites by D.D. Majumder,S. Karan Pdf
Nanocomposites are often found in nature, as a multiphase solid material where one of the phases has one, two or three dimensions of less than 100nm, or structures having nano-scale repeat distances between the different phases that make up the material. In this chapter the magnetic properties of ceramic nanocomposites are presented, along with structures which differ markedly from that of the component materials. It is emphasized that, in the case of nanocomposites, where the main part of the volume is occupied by ceramics (i.e. a chemical compound from the group of oxides, nitrides, borides or silicates, among others), further systematic study will be necessary to improve their optical, electrical and magnetic properties, as well as their tri-biological, corrosion resistance and other protective properties.
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 a targeted set of material properties is, therefore, a daunting task. Since the microstructure involves multiple length scales, multiscale analyses based material design is an appropriate approach for such a task. With this view, this chapter presents an overview of the current state of the art and work performed in this area.

Ceramic nanocomposites by T. Subhani,M.S.P. Shaffer,A.R. Boccaccini Pdf
In this chapter, glass and glass-ceramic matrix composites containing carbon nanotubes (CNTs) are discussed with an emphasis on their production, properties, microstructures and applications. Composite manufacturing routes require both CNT/matrix powder preparation techniques and their densification by suitable sintering processes. Physical, mechanical, functional and technological properties of the composites are evaluated, including density, hardness, elastic modulus, fracture strength and toughness, electrical and thermal conductivity, wear and friction resistance, and thermal shock, cycling and ageing resistance. Microstructural features are typically characterized by X-ray diffraction and scanning and transmission electron microscopy. Based on the characteristics obtained, potential applications of the composites are considered, together with a discussion of the unresolved manufacturing challenges and desirable, but still unattained, properties.
Ceramic nanocomposites by X. Liang,D.M. King,A.W. Weimer Pdf
Ultra-thin films can be coated on primary fine particles without significant aggregation by atomic layer deposition (ALD) in a fluidized bed reactor. Precursor doses can be delivered to the bed of particles sequentially and, in most cases, can be utilized at nearly 100% efficiency without precursor breakthrough and loss, with the assistance of an inline downstream mass spectrometer. A multitude of applications can be addressed in a competitive fashion using fine particles that have been surface-modified using ALD in scalable, high-throughput unit operations. Several examples of the applications of conformal ALD coatings have been discussed, including oxidation-resistant metals or ceramics, coatings that enable biomedical applications including tissue engineering, and corrosion-resistant particles for next-generation batteries, capacitors or fuel cells. It is expected that the technology of thin film coating by particle ALD will play a major role in the field of advanced materials.
