Small-angle Neutron Scattering Measurements on SnO_2 Particles Suspended in Liquid Sn-S Systems
Small-angle neutron scattering measurements were carried out on liquid Sn-0.4mol%SnO<sub>2</sub> (solid spherical particle)-1.1at%S, Sn-0.4mol%SnO<sub>2</sub> and Sn-1.1at%S systems at 723 K. The scattering intensity for Sn-SnO<sub>2</sub> system is proportional to the parameter, <i>Q</i><sup>-4</sup>, while the scattering intensity for Sn-SnO<sub>2</sub>-S system is lower, showing nearly <i>Q</i><sup>-3</sup> dependence. To analyze them, the scattering intensity has been calculated for Sn-SnO<sub>2</sub> and Sn-SnO<sub>2</sub>-S systems with various particle sizes and thicknesses of the surface layer. For Sn-SnO<sub>2</sub>-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.
