description

The Chapter covers the technological aspects of many chemical and physico-chemical nanofabrication methods relevant to making nanoferroic materials and composites. First, the classification of relevant synthesis methods of nanoferroics has been presented. Synthesis of particular nanoferroics with different chemical bonding like metallic, oxide and non-oxide compounds is considered in details. Among the methods, the mechanochemical, sonochemical, hydrothermal, co-precipitation, emulsion, thermal decomposition of unstable precursors have been analyzed. The competition between new phase nucleation and nuclei growth has been revealed to be controlled using feedback between reaction rate and temperature. Agglomeration of nanoparticles has been studied as a phenomenon typical for nanoparticles. Surfactants are used for the synthesis of nanoparticles to reduce the interparticle interaction due to increased repulsive forces to control the particle size and their distribution in most chemical methods. We present a comparative analysis of strengths and weaknesses of all available methods for nanoferroics fabrication.
