Abstract
This paper presents a detailed analysis of the synthesis of spinel MgAl2O4, a material with key industrial applications, through the calcination of brucite and alumina. The study reveals that a longer heat treatment time at 960°C favors the formation of spinel with spherical morphology and reduces the presence of MgO in irregular agglomerates. XRD analyses confirm the progressive phase transformation, while SEM-EDS provides evidence of chemical composition. These findings support the use of the Avrami equation to model spinel formation kinetics and highlight the importance of optimizing calcination parameters to improve material properties. The study concludes with an improved route for the efficient production of MgAl2O4, which could significantly influence its application in demanding environments.
