Abstract

Small-angle neutron scattering measurements were carried out on liquid Sn-0.4mol%SnO 2 (solid spherical particle)-1.1 at%S, Sn-0.4mol%SnO 2 and Sn-1.1 at%S systems at 723 K. The scattering intensity for Sn-SnO 2 system is proportional to the parameter, Q -4 , while the scattering intensity for Sn-SnO 2 -S system is lower, showing nearly Q -3 dependence. To analyze them, the scattering intensity has been calculated for Sn-SnO 2 and Sn-SnO 2 -S systems with various particle sizes and thicknesses of the surface layer. For Sn-SnO 2 -S system, the best fit with the experimental data has been obtained for a particle size of 4 μm and the surface layer thickness of 100 A, consisting of S.
