Abstract
This work is based on an article under review with a journal.1 Magnesium orthotitanate or qandilite (Mg2TiO4) refractory aggregate is an emerging environment-friendly, chromium-free raw material that can be used to develop bricks replacing traditional, yet carcinogenic hexavalent chromium forming magnesia-chrome (MgO-Cr2O3) refractories used in copper converters. Whereas the synthesis, thermal and physical properties of Mg2TiO4 aggregates have been reported in the literature, its corrosion resistance, especially against copper converter slags with varying iron to silica ratios remains unknown. Three synthetic copper slags with Fe/SiO2 ratios of 1.5−2.2 and containing small amounts of lead and copper oxides along with calcia, magnesia and alumina, mimicking industrial converter, were prepared. Hot stage microscopy was used to understand the variation in wettability of the three slags on dense Mg2TiO4 aggregate substrates having only 1% open porosity. Cross-sectional SEM-EDS was performed after cooling to reveal the corrosion mechanism.
