In-Situ Observation on the Agglomeration and Dispersion of Particles at the Interface of High-temperature Melts

The aggregation and dispersion behaviors of particles at a gas-liquid interface have been brought to the forefront of research in recent years because of their importance in numerous applications, such as the extraction and separation of ore particles in aqueous systems, metallic materials with high purity, novel nanostructured materials with self-assembly particles, pharmaceutical products, food and emulsions.1–10) The aggregation of particles in metallic materials destroys their mechanical properties and fatigue life. The interactive behavior affects the materials assembly, encapsulation, and emulsion stabilization.4,11–13) Colloidal particles and protein macromolecules confined in liquid films show attraction forces and form clusters with a high degree of order.14–18) Therefore, the aggregation and dispersion behaviors of particles at a gas-liquid interface must be well understood and controlled.
