Abstract

This study reports on synthesis of nano sized mixed oxides ZnFe2O4 was prepared by novel self combustion method using urea as afuel. The processing features and the micro structural characteristics of ZnFe2O4 phases formed during self combustion reaction ofthe gels have been investigated by TG-DTA, SEM, XRD, and EDX and TEM. It has been found that the nanoscale compositepowders of ZnFe2O4, directly obtained through the in situ self combustion reactions within the gel are composed of looselyagglomerated particles with sizes of ~100 nm, while these particles themselves are the aggregates of finer ZnFe2O4 and crystallitesof 22- 32 nm in size. The densities of sintered oxides evaluated by different methods are a,roximately same. The superhydrophilicityof the sintered oxides was investigated by wetting experiments, by the sessile drop technique, were carried out at room temperaturein air to determine the surface and interfacial interactions.
