Abstract
Magnesium aluminum ferrite brick has excellent physical properties and good resistance to alkali salt erosion. It is widely used in cement rotary kiln firing zone and is one of the best refractory materials for replacement of magnesium chromate brick. In this study, the magnesium aluminum ferrite spinel was prepared by microwave sintering using magnesium oxide, aluminum oxide and ferric oxide as raw materials. Its generation mechanism was identified by analyzing the phase transformations and microstructure changes of the spinels prepared at different sintering temperatures for variable time using the X-ray diffraction (XRD ) and scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM -EDS).
