A Study of Citric acid on the Properties of nano MnZn Ferrite Powders

摘要

In order to prepare MnZn ferrite with more uniform dispering, the citric acid were used as the activating agent. X-ray diffraction(XRD) and transmission electron microscopy (TEM) were used to characterize the phase and the microstuctures of the samples. The magnetic properties of the ferrite were examined by vibrating sample magnetometer(VSM). Compared to effectes of the citric acid were added at different stage on the magnetic properties MnZn ferrite, the results showed that: the combination properties of powders which were ultrasonic dispersed in post treatment on citric acid was better than fore treatment one.
