掺杂对功率铁氧体磁性能的影响

Effect of different dopants on properties of low power loss MnZn ferrites

研究了不同的掺杂组合对 MnZn功率铁氧体磁性能的影响。并与传统的最常用的 CaO SiO2 做了比较。我们还发现 Ca、Ta 和 Nb 离子作为一组掺杂,组以适配的工艺条件,可以取得比常用的 CaO SiO 更好的结果。

We studied the effect of the different dopants in the manganese-zinc ferrites on the low power loss by measuring the magnetic properties and observing the grain boundary structures in this paper. The results was compared to the result of CaO-SiO2 used commonly. We have found that Ta2O5- Nb2O5-CaCO3 as an association obtained better quality at optimum processing conditions.
