| Abstract Scope |
This study provides an analysis of the properties of spinels Fe(1-x)Zn(x)Cr2O4 obtained by hydrothermal synthesis. Experiments were conducted where changes were made to the pH, the concentration of precursor salts and the type of iron salt used. The response variables analyzed were the distribution of phases, color, particle size distribution, chemical composition and shape of particles. The methods used to characterize the spinels obtained were by X-ray diffraction (XRD), UV-VIS-NIR spectroscopy, scanning electron microscopy (SEM), energy dispersion X-ray analysis of (EDX) and thermal analysis (DTA/TGA). Results are compared with a commercial product obtained by traditional method of solid state synthesis at high temperature. It is hoped that this study will serve as a technical option for the development of alternate routes for spinels production so as to provide environmental benefits, economic and technology compared to traditional methods. |
