摘要：
Nanocrystalline zinc ferrite (ZnFe2O4) powders have been synthesised successfully by high power short-pulse electric discharge of Fe and Zn wires in oxygen gas. The powders were characterised by X-ray diffraction and transmission electron microscopy (TEM). Mean site 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.
