Abstract
Abstract In this work, formation of MgFe 2 O 4 nanoparticles by the decomposition of co-precipitated magnesium and iron hydroxides between 300 and 450 °C temperatures and 500 atm water vapor pressure was studied. Decomposition mechanism and conditions of co-precipitated hydroxides was investigated by using XRD, FT–IR, SEM–EDS and simultaneous TG–DTA–MS analyses. It was found that magnesium and iron hydroxides were co-precipitated as amorphous layered double hydroxides (LDHs) and formation of MgFe 2 O 4 nanoparticles took place via decomposition of LDHs as spatially separated thermodynamic stable phases under hydrothermal conditions. Crystallite sizes of the MgFe 2 O 4 synthesized were calculated as in the range 45–60 nm. Comparison of thermodynamic calculations and experimental results showed that kinetic hindrances leaded to increase in theoretical formation temperature of MgFe 2 O 4 .
