Abstract

In this paper, the interface reaction between different acidity and alkalinity of slag was explored by comparing the changing of wetting angle and viscosity in the interface between the binary slags. And the results indicated that, the reaction temperature range of Al₂O₃ and basic slag was relatively larger when the reaction interface was acid slag, and the fusion temperature would change when the content of calcium and magnesium were changed in the base slag. Al₂O₃, SiO₂ are prone to react with other components and formed the new silicate phase compared to CaO, MgO, what made interfacial diffusion relatively better.

Keywords

molten slag wetting; acidity/alkalinity; viscosity; fusion temperature; scanning electron microscope (SEM)
