Planar laser-based imaging measurements of fluorescence and particle scattering have been obtained during flame synthesis of the iron-oxide/silica superparamagnetic nanocomposites. The results indicate that the vapor phase FeO concentration is very sensitive to the amount of precursor added, indicating a nucleation controlled growth. The FeO vapor concentration in the main nucleation zone was insensitive to the amount of silicon precursor injected, implying that nucleation of each component occurred independently from the other. 

Generally, the inorganic materials used to prepare the nanocomposites mainly include layered silicate clay, layered compounds, metal powder, and a variety of inorganic oxides. In our research works, nanosized zinc oxide, iron oxide, silica, and YIG particles were synthesized and used to prepare a variety of polymer nanocomposites, giving the composite materials many new features. This chapter based on our research discusses the methods of preparation and characterization of the polymer-inorganic nanocomposites. 

Recently, several metal oxides apart from silica have been investigated and reported for mbber-based nanocomposites. Some important and commercially meaningful oxides used in rubber are zinc oxide (ZnO), magnesium hydroxide (MH), calcium carbonate, zirconate, iron oxide, etc.
