摘　　要：注浆成型永磁铁氧体的磁性能与原始料浆颗粒的大小密切相关。通过工厂跟踪试验和实验室测试,深入分析了SrFe12O19永磁铁氧体料浆颗粒大小对烧结后磁体的晶粒取向度、晶相结构和最终磁性能之间的关系。结果表明,料浆原始颗粒越小,则晶粒取向度越大,样品磁性能越好。The magnetic properties of the slip casting shaped hard ferrite strongly depend on the original slurry granularity. In this paper, through tracking the real production process and the lab experiments, the effect of the slurry granularity of the SrFe12O19 hard ferrite on the grain alignment degree, crystal structure and the magnetic properties is analyzed thoroughly. It＇s found that with the decreasing of the grain sizes of the slurry, the grains turn to align coherently and the magnetic properties of the ferrite turn to be better.
