| 摘 要： | 用精矿粉代替Fe2O3、用Mn3O4代替MnCO3作为原材料，因为减少了Mn离子在反应中的变价机率，提高了配方中Mn离子的准确性，精矿粉的主要成分Fe3O4相变为α-Fe2O3的温度与Mn铁氧体生成温度接近，所以使固相反应更安全，能制备出高性能功率软磁MnZn铁氧体。适量的掺杂CaCO3、V2O5及Bi2O3可以进一步降低样品功耗；制备过程中，采取一些特殊工艺措施及适当烧结温度能进一步提高样品磁性能，使其综合性能基本达到日本TDK的PC30水平。

| Abstract: | Excellent MnZn soft ferrite materials have been prepared with refined iron-mineral powders and Mn-3O 4.Mn 3O 4 in place of MnCO 3 can reduce the rate of Mn's changing ion vaue and refined iron-mineral's phase change temperature is similar to Mn ferrite forming temperature.The two factors make solid phase reaction of forming MnZn ferrite carry out more completely.Adding CaCO 3,V 2O 5 and Bi 2O 3 rightly can reduce the power loss of samples.Some special technology and proper sintering temperature can improve the magnetic properties of samples.As a result,the ferrite materials are similar to PC30 of TDK. |
