Resumo
Light scattering, electron microscopy and X-ray diffraction are used to determine the morphology and size of particles in diluted aqueous gel of tin (IV) oxyhydroxide. Data show that the gel is composed of spherical 2-3 nm sized crystalline particles aggregated as rigid branched chains. It is suggested that stiffness of chains results from dissolution-precipitation equilibria and chemical bonding between particles within the chains. © 1994.
