Outline of Final Research Achievements

Interfacial phenomena like wetting and emulsion, which occur at the interface of substances, are a crucial for high temperature process like material processing. Therefore, a lot of efforts are focused on the need to measure the interfacial tension values. In the present work, the applicant’s invented method for measuring interfacial tension of liquids based on the profile of a floating droplet is applied to the measurement of interfacial tension between liquid Pb and molten salt. The measurement of interfacial tension of liquid Pb/molten chloride salt mixtures and liquid Pb/molten carbonate salt mixtures was succeeded, which means the invented method is available for the measurement of interfacial tension at high temperature.
