A Comprehensive Study on Synthesis of MgFe2O4 Nanoparticles; Influence of Fuel
摘要
Magnesium ferrite nanoparticles (MgF) have been synthesized by straight forward solid-state combustion approach. In combustion synthesis, fuel and adiabatic flame temperature are the most scalability parameters. The outcome of various fuels (Egg white, Citric acid, Glycine, and Urea, etc.) on structural and magnetic properties was studied in detail. An understanding of the mechanism of combustion reaction based on the calculation of the adiabatic flame temperature and the quantity of gases released throughout the reaction has been proposed. In the present investigation, egg white shows great magneto–structural as well as thermal properties due to higher gas evolution, biogenic content in it, which assists the material towards biocompatibility, and shows rapid combustion as compared to reported conventional chemical fuels. The crystallite size calculated with the plane (311) of MgF is varied from 27.68 to 49.2 nm. High-resolution transmission electron microscope (HR-TEM) results confirm the formation of smaller particles with an average particle size range from 23.78 ± 4.2 to 56.43 ± 7.1 nm. Saturation magnetization (Ms) values obtained from the vibrating sample magnetometer are found to be 29.5 emu/g, 27.49 emu/g, 24.75 emu/g, and 23.80 emu/g for Egg white, Glycine, Citric acid, and Urea, respectively.
