Abstract
Nanocrystallites ferrite particles (ZnFe2O4, CoFe2O4) have been synthesized successfully by high power short electric pulse discharge of Fe and metal wires in oxygen. The powders were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Mean size of the obtained particles strongly depended on the oxygen pressure, which were determined by both BET and TEM. TEM observation shows that the well dispersed, uniform sized ferrite nanocrystallites was synthesized.
