混合溶剂—沉淀法制备纳米MgFe_2O_4及XRD测定

PREPARATION OF NANOMETER MgFe_2O_4 BY THE METHOD OF MIXED SOLVENT PRECIPITATION AND XRD DETERMINATION

在乙醇—水混合溶剂中 ,采用沉淀法首先制备 Mg( OH) 2 -Fe( OH) 3 混合沉淀物 ,再经高温晶化制得了Mg Fe2 O4,经 X-射线衍射 ( XRD)

The mixture precipitation of Mg(OH) 2 Fe(OH) 3 was prepared by the method of precipitation in the mixed solvent of alcohol water first,and then it was crystallized in high tempreture and formed MgFe 2O 4.MgFe 2O 4 is a type of nanometer spinel particle which is determined by XRD.
