Abstract

We have studied the ceramic liquid droplet of Cu Ox -added Bi Ox at high temperature in vacuum. Cu Ox always floated on the Bi Ox as a surfactant and suppressed the evaporation of volatile Bi Ox liquid droplets. A clear liquid behavior of the Bi Ox droplets was directly observed by in situ laser microscope, with numerous liquid droplets growing by the coalescences in accordance with Marangoni's [Nuovo Cimento Ser. 2, 239 (1872)] effect involved with the precursor film. We have also found a unique absorption of CaO into the Bi Ox liquid droplets, based on which a reliable process has been established for an atomically flat surface of MgO(001). These results open a broad window of opportunity to tailor not only a chemical interaction on oxide surface but also a liquid droplet dynamics in vacuum.
