Abstract:
Single phase cubic spinel of the composition Mn1.5Al1.5O4 is synthesized. Its crystal structure refinement shows that 0.4Mn+0.6Al are in the octahedral sites and 0.7Mn+0.3Al are in the tetrahedral sites. High temperature X-ray diffraction is used to analyze Mn1.5Al1.5O4 behavior during heating and cooling in air. In a temperature range of 600°C to 700°C, initial spinel splits into layers, and the sample represents a twophase system: cubic spinel Mn0.4Al2.4O4 and a phase based on β-Mn3O4. Above 900°C the sample again turns into single phase cubic spinel. The role of oxidizing processes in the decomposition of Mn1.5Al1.5O4 caused by oxygenation and partial oxidation of Mn2+ to Mn3+ is shown. A scheme of structural transformations of manganese aluminum spinel during heating from room temperature and cooling from 950°C is proposed.
