Phase equilibria study in the system “Fe2O3”-ZnO-Al2O3-(PbO+CaO+SiO2) in air

Thermodynamic equilibrium approach to predict the inorganic interactions of ash from biomass and their mixtures: A critical assessment

“…According to the documentation file of the FToxid database, slag A is a liquid solution of various oxides that can dissolve sulfur as sulfides. Therefore, it is more used in literature than slag B [31][32][33]. In contrast, the FactSage description of Slag B says that it is a liquid solution of various oxides that can dissolve sulfur as sulfates as a dilute solution with a maximum concentration of 10 wt.%.…”
