Small-angle neutron scattering measurements were carried out on liquid Sn-0.4mol%SnO₂ (solid spherical particle)-1.1at%S, Sn-0.4mol%SnO₂ and Sn-1.1at%S systems at 723 K. The scattering intensity for Sn-SnO₂ system is proportional to the parameter, Q^-4, while the scattering intensity for Sn-SnO₂-S system is lower, showing nearly Q^-3 dependence. To analyze them, the scattering intensity has been calculated for Sn-SnO₂ and Sn-SnO₂-S systems with various particle sizes and thicknesses of the surface layer. For Sn-SnO₂-S system, the best fit with the experimental data has been obtained for a particle size of 4μm and the surface layer thickness of 100 Å, consisting of S.
