Summary

Commercially available, 10 nm sized tin oxide cores were coated with silica by sol-gel processing using tetraethoxysilane (TEOS) to give monodisperse tin oxide-silica particles of the core-shell type. By controlling hydrolysis and condensation the size of the resulting spheres was varied in the nanometer range. Particle morphology and composition was characterized by electron microscopy, dynamic light scattering, N2-sorption (BET) and X-ray fluorescence. As a consequence of the tin oxide content numerous possible applications arise, for example introducing X-ray opacity in dental filling materials. In order to effectively use such particles as fillers an additional organic surface functionalization was created matching the functional groups of the polymeric resins, e. g. ORMOCER®s (inorganic-organic copolymers).
