摘要:

本文采用共沉淀法制备了锰锌铁氧体前驱体粉末,对其进行压块处理后,通过烧结得到锰锌铁氧体。测试分析了锰锌铁氧体的X射线衍射及磁性能,并对其生物相容性进行了测试与分析。结果表明,经过烧结的样品为单一的尖晶石相锰锌铁氧体。所制得的锰锌铁氧体具有较高的磁化率,锰锌铁氧体的磁化率随着含锌量的降低、含铁量的增加而逐渐升高。加入了磷酸氢钙的样品在模拟体液中培养三周后,有羟基磷灰石生成,样品具有良好的生物活性和相容性。
>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.
