Modification of interface chemistry and slag structure by transition element Cr
TL;DR: In this article, a comparative study on CaO-MgO-Al2O3-SiO2 slags and CaO−Mg O-Al 2O3−SiO 2 slags was conducted to investigate the distribution of the elements at the gas-slag interface, which revealed that sulfur exists in the form of S2− in the slag.
