Preparation of ZnFe_2O_4 by hydrolyzing Zn/Fe_3O_4 nano-particles

Zn nano-particles were prepared by a dry roller vibration milling at room temperature,Fe3O4 nanoparticles were prepared by chemical precipitation method,and then ZnFe2O4 nano-particles were manufactured by hydrolyzing Zn/Fe3O4 nano-particles.TEM and XRD tests showed that Zn particles size milled 11h was the range between 10 and 20nm,Fe3O4 particles size was about 20nm and the solid product of the hydrolysis was also about 20nm with quadrate nano-flake morphology.The research indicated that it was optimal reaction condition for making ZnFe2O4 when reaction temperature was 300℃ and mol ratio(Zn:Fe3O4)equal to 1.5:1.It is obvious that Zn nano-particles milled 11h provided with excellent performances,which could make the chemical reaction complete rapidly in a lower temperature.The preparation method was comparative simpleness and prone to a batch production.
