Abstract
Recently, a new high-temperature ternary Cr(III) phase (Wuboraite, CaAl2Cr2IIIO7) was synthesized in the Al2O3–CaO–Cr2O3 system. However, its formation & chemical transformation mechanism is yet to be explored in detail. And here, we investigated the system between 500 and 1600 °C under the air and argon (Ar) atmosphere via solid-state reaction using XRD, TG-DSC, XPS, and leaching tests. Wuboraite formation starts at different temperatures (∼1500 & ∼1100 °C) under different atmospheres (air and Ar). The intermediate compounds, CaCrVIO4 and CaCr2IIIO4, formed under air and Ar atmospheres, play a crucial role in wuboraite conversion given proper temperature and stoichiometry.
