Abstract
An innovative method to calculate the thickness of gas–slag boundary layer is proposed in CaO–SiO2–10 wt pct MnO at 1873 K. The samples were kept under Ar–CO–CO2–SO2 atmosphere for different time. The thickness can be derived from etching time, etching rate, and the structure information correspondingly. The calculation results show that the boundary layer thickness of 1, 3, and 6 hours is 117.90, 102.18, and 94.32 nm, respectively, which is attributed to the Mn–S interaction and accumulations in the interface layer.
