【摘要】 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。更多还原

【Abstract】 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.更多还原
