Effects of BaO Content and CaO/Al2O3 Ratio on the Properties and Structure of Aluminate Slag

To explore the relationship between typical components, structure, and properties, provide theoretical guidance for non-reactive aluminate slag, effects of BaO content CaO/Al2O3 (C/A) ratio on microstructure properties slag were investigated with Fourier-transform infrared Raman spectroscopies, hemisphere melting temperature apparatus, rotating viscometer, four-electrode conductivity tester in this study. The results showed that, when contents changed from 2 to 10 wt pct C/A 1.2 1.4, more complex Al–O network transformed into simpler structure. Meanwhile, combing minimally, indicating degree superheat slightly influenced viscosity, viscosity was mainly by polymerization degree. Owing increased Ba2+ Ca2+ concentration decreased increased. Furthermore, increasing decreasing ratio, break viscosity–temperature curve decreased. This trend related precipitation mineral phases Ca12Al14O33, CaF2, BaAl2O4. It also shown that a high low help improve lubricating slag.
