Description
Summary:In this study, M g F e 2 O 4 nanoparticles with different M g / F e molar ratios were synthesized by a sol-gel (Pechini) method and a Support Vector Regression (SVR) as a predictive model has been used in this context for the first time. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to characterize the nanoparticles synthesized using this methodology. According to the results obtained by XRD, nanoparticles with a M g / F e ratio of 0.75 heat-treated at 700 o C have an inverse spinel structure, which corresponds to the pure magnesium ferrite phase. The use of the SVR predictive model allowed the efficient synthesis of a pure magnesium ferrite phase, providing data that could be experimentally validated to obtain a pure phase without additional phases. Graphical Abstract Highlights SVR is applied as a model prediction for pure MgFe 2 O 4 nanoparticles. Synthesis leads to magnesium ferrite nanoparticles without additional phases. Structural characterization of magnesium ferrite nanoparticles by X-Ray diffraction. The potential application of MgFe 2 O 4 nanoparticles focuses on biomedical industry.
