MgO/Al2O3ratioBlastfurnaceslagVISCOSITYIRONMAKINGPhasediagramIn recent years, more and more high Al2O3 iron ores were used in East Asia, especially in China, which increased the Al2O3 content in blast furnace (BF) slag and resulted in poor metallurgical properties of slag. Adding MgO-bearing...
首先打开FactSage软件的Phase Diagram相图计算模块,在Components栏下输入第一个组分CaO后,再点击+依次输入另外两个组分Al2O3和SiO2。 打开Units窗口选择合适的单位,这里温度选择℃,质量选择g为单位。对于CaO-Al2O3-SiO2体系,Data Search窗口中选择氧化物数据库[FToxid]。然后点击Next进入下一步。 选择计算中可能涉及...
-While alumina has a reputation for being super refractory, other pure oxides like CaO and MgO actually melt much higher! But the difference is that when alumina particles are combined with those of other oxides it maintains its refractory character while the others interact and become fluxes. -...

This was also observed for the electric field enhanced reaction of In2O3 and MgO [11], [16]. The observed pore formation in the interface between the Y2O3 and YAM phase, respectively in the bulk of the Y2O3 phase, is most likely due to the presence of electronic conductivity at the ...
