Abstract

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.
