摘　　要：介绍了麦格磁电科技(珠海)有限公司开发的宽温、高磁导率锰锌软磁铁氧体材料M10T。这种铁氧体材料采用传统的氧化物干法工艺制作,研究了原材料、主配方和TiO2掺杂等因素对材料磁导率的影响。结果表明,选择新日铁CSR900为氧化铁,材料的起始磁导率最高;主配方氧化铁含量在52.5mol%,可以获得较好的磁导率的宽温特性;掺杂氧化钛含量在100×10-6,磁导率的宽温特性最好。Soft ferrite material M10T with wide operation temperature and high permeability was prepared by traditional dry oxide process, and influence of raw material, main component and addition of TiO2 on the initial permeability was investigated. The results indicate that sample form CSR 900 iron oxide has the highest permeability, sample with 52.5mol%iron oxide exhbits better temperature dependence of permeability, and addition of 100 ppm TiO2 resultes in good temperature dependence of permeability.
