1. Thermodynamic Studies of the Fe-Pt System and “FeO”-Containing Slags for Application Towards Ladle Refining
Detta är en avhandling från Stockholm : MaterialvetenskapSammanfattning : In the present work, the thermodynamic activites of ironoxide, denoted as "FeO" in the slag systems Al2O3-"FeO", CaO-"FeO", "FeO"-SiO2, Al2O3-"FeO"-SiO2, CaO-"FeO"-SiO2and "FeO"-MgO-SiO2were investigated by employing the gasequilibration technique at steelmaking temperatures. Thestrategy was to expose the molten slag mixtures kept inplatinum crucibles for an oxygen potential, determined by aCO/CO2-ratio. LÄS MER
2. Measurements of the thermodynamic activities of chromium and vanadium oxides in CaO-MgO-Al2O3-SiO2 slags
Detta är en avhandling från Stockholm : MaterialvetenskapSammanfattning : In the present work, the thermodynamic activities of chromium and vanadium oxide in CaO-SiO2-MgO-Al2O3 slags were measured using gas-slag equilibration technique. The slag was equilibrated with a gas mixture of CO, CO2 and Ar gases enabling well-defined oxygen partial pressures in the gas mixture (PO2=10-3,10-4,10-5 Pa) at temperatures 1803, 1823K, 1873, 1923 K.

3. Thermodynamic studies of some iron oxide-containing slag systems
Detta är en avhandling från Institutionen för tillämpad processmetallurgiSammanfattning : In the present investigation experimental measurements ofthe thermodynamic activities of iron oxide in the systems:Al2O3-FeO, CaO-FeO,FeO-SiO2 and, CaO-FeO-SiO2 wereperformed by using gas equilibration technique. Theexperimental measurements were performed in the temperaturerange 1823-1923 K for the binary systems and, at 1873 K for theternary system respectively. LÄS MER
