| Abstract: | Nanocrystalline zinc ferrite (ZnFe2O4) powders have been synthesized successfully by high-power short-pulse electric discharge of Fe and Zn wires in oxygen gas.
The powders were characterized by X-ray diffraction and transmission electron microscopy (TEM). Mean size of the obtained
particles determined by both BET and TEM was 12 to 56 nm depending on the oxygen pressure. X-ray analysis showed that the
zinc ferrite spinel was clearly obtained.
