摘　　要：应用化学共沉淀法制备了NiZn铁氧体的前驱体粉末。对前驱体在1 240℃热处理后,得到尖晶石型NiZn铁氧体样品。用X射线衍射(XRD)和扫描电子显微镜(SEM)对其进行表征,结果表明:样品的晶体形貌为准六角形,粒径DSEM≈3.5μm,而DXRD≈80 nm,即DSEM≈44DXRD,这是NiZn铁氧体制备领域一个新颖的结果。Nanosized NiZn ferrite powders were prepared by co-precipitation method. The prepared powders were sintered at 1 240℃ in air. The phase structure and morphology of NiZn ferrite powders were studied by X-ray diffraction and scan electron microscopy, The results show that the crytal morphologies are quasi-hexagon, and the size of the nanosized NiZn ferrites is DXRD≈80nm, while DSEM≈3.5 μm, i.e DSEM≈44DXRD which is an interesting novel result.
