| Abstract Scope |
Al2O3-MnO-SiO2 is an important base system related to steelmaking, silicomanganese production and lithium ion battery treatment. Phase equilibria in this system have been extensively and repeatedly studied since 1934 due to significant discrepancies. The early experimental studies were carried out under nitrogen gas flow which was considered as inert atmosphere. Recent studies showed that nitrogen can dissolve into the oxide melts causing different liquidus temperatures and compositions. Clearly the experimental data and system have to be identified to be N-containing and N-free for various applications. Careful experiments and comparison of experimental techniques explained the discrepancies in this system reported by different researchers. Thermodynamic modeling calculations are also performed for the N-containing and N-free systems to demonstrate the importance in selection of the parameters. |
