摘要：

Crystal structure refinement was carried out on a defect spinel with composition Mg0.388Al2.408O4 synthesized at 2050-degrees-C. Combining information from site occupancies and bond distances for tetrahedral and octahedral sites, the following cation and vacancy distribution were obtained: (Al0.653Mg0.347)(Al1.755Mg0.041-square-0.204)O4. Structural analysis performed after heating the same crystal at 1150-degrees-C led to the same result, suggesting that the obtained distribution is stable over a wide range of temperatures.
