Characterization of size and morphology of ZnO and Fe2O3 nanoparticles in dispersive media by SAXS

The size and shape of ZnO and Fe2O3 nano-particles in 1% sodium carboxy methyl cellulose were meas-ured by small-angle X-ray scattering(SAXS) of synchrotron radiation.Compared with the TEM results,the SAXS results indicated that the ZnO and Fe2O3 nano-particles in 1% sodium carboxy methyl cellulose were agglomerated.However,the size and shape of the agglomerated particles were almost unchanged along with the increase of particle concentration,indicating that the particles in 1% sodium carboxy methyl cellulose were stable.
