Formulating the effects of concentration (x) and calcination temperature on the synthesis of Mn_1−xZn_xFe₂O₄ by using response surface methodology

The effect of stoichiometric concentration (x) and calcination temperature on the lattice constant and particle size of Mn1−xZnxFe2O4 was investigated while using co-precipitation method to prepare nano-sized ferrite particles. Crystallographic studies were used to determine the lattice constant and particle size. The process variable values (concentration (x) and calcination temperature) for 13 runs were proposed using response surface methodology (RSM). Optimized values predicted by RSM for the concentration and calcination temperature were 0.74 and 996 °C respectively, for lattice constant 8.36625 Å and particle size 14.81 nm. The optimization of parameters by using RSM may be helpful in the synthesis low cost manganese zinc ferrite using the co-precipitation technique.
