Study on Preparation and Biocompatibility of Mn-Zn Ferrites

Mn-Zn ferrite precursor powder was prepared by co-precipitation method. The Mn-Zn ferrite was obtained by sintering after being pressed. XRD and magnetic properties of the Mn-Zn ferrite were analyzed. And its biocompati- bility was tested and analyed. The results show that it is in a single phase of Mn-Zn ferrite spinel after sintering. The Mn-Zn ferrite possessed high magnetic susceptibility. The magnetic susceptibility of ferrite increased gradually with the zinc volume reducing and the iron content increasing. After three weeks of cultivation in simulated body fluid, there is hydroxyapatite in the samples adding calcium hydrophosphate, and the sample has good biological activity and com- patibility.
