Characteristics of Fe2O3/SiO2 Nano-Composites Particles Prepared by a Diffusion Flame with Premixed Precursor
Fe2O3 nano-particles coated with SiO2 are synthesized using H2/O2 co-axial diffusion flame with the state-of-the-art electro-spraying (e-spray) technique at atmospheric condition. Fe(CO)5 and TEOS (tetra-ethyl-ortho-silicate) mixture in liquid phase is injected directly into the center of the flame using the electro-spraying method. The synthesized particle characteristics are analyzed with HRTEM, XRD, SQUID. The core (iron oxide)-shell(silica) structured spherical particles are obtained. Most of the particles synthesized are magemite() regardless of the particles sampling positions inside the flame.
