초록

The ZnFe2O4 powder were prepared under glycothermal conditions by precipitation from metal nitrates with aqueous potassium hydroxide. Ultrafine particles of the ZnFe2O4 were obtained at temperatures as low as 225-300$^{\circ}C$. The microstructure and phase of the ZnFe2O4 powder was studied by SEM and XRD. The properties of the powder were studied as a function of various parameters (reaction temperature, reaction time, solid loading). The average particle diameter of the ZnFe2O4 increased with increasing reaction temperature. After glycothermal treatment at 270$^{\circ}C$ for 8hrs., the average particle diameter of the ZnFe2O4 was about 50 nm.
