| Abstract: | Nano-crystalline MnZn ferrites,ZnxMn1-xFe2O4(x=0.2-0.4),were produced by the high energy milling method with high pure iron oxide prepared by chemical precipitation process as the starting material.Their structural properties were analyzed and characterized by means of X-ray diffractometer(XRD)and scanning electron microscopy(SEM).The results showed that formation of the nano-crystalline MnZn ferrites had two stages:the phase of ZnMn2O4 grew in the presintering first and then turned into Zn0.2Mn0.8Fe2O4 during the sintering process.The crystal growth mechanism was compendiously discussed. |
