The System MgO-Cr2O3−Fe2O3 at 1300°c in Air
Phase relations in air at 1300°C were determined for the system MgO‐Cr2O3−Fe2O3 by conventional quenching techniques. Details of the phase equilibria were established for: (1) the sesquioxide solid solution between Cr2O3 and Fe2O3, (2) the spinel solid solution field between MgCr2O4 and MgFe2O4, and...

| Zusammenfassung: | Phase relations in air at 1300°C were determined for the system MgO‐Cr2O3−Fe2O3 by conventional quenching techniques. Details of the phase equilibria were established for: (1) the sesquioxide solid solution between Cr2O3 and Fe2O3, (2) the spinel solid solution field between MgCr2O4 and MgFe2O4, and (3) the periclase solid solution field for MgO. Selected tie lines connecting coexisting compositions were established with X‐ray diffractometer data. Diffuse reflectance spectra, diffractometer intensity ratios, and lattice parameter measurements were obtained for quenched samples to study the structural inversion in the spinel series MgCr2O4‐MgFe2O4. |
