Due to the potential high-temperature application of nanocomposites, as well as the fact that metal-reinforced ceramic nanocomposites combine metal and non-metal phases in equilibrium, it is important to understand the oxidation resistance of such materials. Using the Ni-alumina system as an example, and following Sekino et al.,12 the partial pressure of oxygen required to prevent the formation of nickel spinel (NiAl204) from a two-phase mixture of Ni and A1203 can be described as 58,59...

Nanophase materials feature a three-dimensional structure and a domain size of less than 100 nm. They are usually produced by compaction of a nanoscale powder and are characterized by a large number of grain boundary interfaces in which the local atomic arrangements are different from those of the crystal lattice [11.2]. Nanocomposites, in contrast, consist of nanoparticles that are dispersed in a continuous matrix, creating a compositional heterogeneity of the final structure. The matrix is usually either ceramic or polymeric. Only the manufacturing of ceramic nanocomposites applies the principles of agglomeration (Section 6.7). 

The pyrolysis of PESs within the channels of the mesoporous silica MCM-41 and the creation of nanostructured magnetic ceramic nanocomposite materials has been achieved. In addition, use of a sacrificial porous alumina yields organometallic and magnetic ceramic nanofibers. Hyperbranched PFSs have also been synthesized and pyrolysis of these interesting materials has been found to lead to superparamagnetic ceramics. Furthermore, pyrolysis of PFSs with pendant Co clusters yields ceramics containing hybrid Fe/Co nanoparticles. ...

Due to the maturation of fabrication materials and methods, ZrO transformation toughened nanoceramics have immense potential of commercialization for orthopedic use. In fact, the European Nanoker integrated project, operated since 2005, is dedicated to commercializing structural ceramic nanocomposites of ZrO and AI2O3 for resurfacing ceramic orthopedic implants such as hip resurfacing and unicondylar knee prostheses [85,100]. Prototypes of such resurfacing implants based on ceramic nanocomposites have been produced in the framework of the Nanoker project and launch of the products is planned.
