SURFACE INTERACTION BETWEEN MOLTEN OXIDES AND REFRACTORY METALS,

Abstract

The results of an experimental investigation of the processes of the wetting of refractory metals by molten oxides and of the spreading of molten oxides over the surfaces of refractory metals are presented. It is shown that the wetting and spreading of molten oxides over the surface of refractory metals is determined by the intensity of the chemical reaction occurring at the interface. The highest spreading rate is observed for the least chemically active metal. These findings confirm that chemical interaction rather than Van der Waals or Coulomb forces plays the dominant role in the processes of spreading in oxide-metal systems.
