Parametrs controlling by Taguchi experimental design for synthesis of MgO-CeO2 nano powder

In this study، CeO2-MgO nanopowder was synthesized via co-precipitation method using cerium (III) nitrate hexahydrate and magnesium nitrate hexahydrate as precursors، and aqueous ammonia solution as a precipitating agent. The Taguchi experimental design has been used to optimize the critical parameters to achieve a smaller particle size of CeO2-MgO nanopowder. The studied parameters were pH، temperature، and concentration of soluble elements. The prepared samples were characterized by X-ray Diffraction (XRD)، and Scanning electron microscopy (SEM). X-ray diffraction revealed that MgO and CeO2 phases were formed. The determined optimum operating conditions were a pH value of 11، temperature of 5 and concentration of 0. 1 M. Under these optimal conditions، average particle size of 30 nm has been obtained.
