摘　　要：采用丝网印刷方法来制备钡铁氧体(BaFe12O19)厚膜,研究了轧制时间和取向磁场强度对BaFe12O19厚膜样品的微观结构和磁性能的影响规律。结果表明,随着轧制时间的增加,所制BaFe12O19厚膜样品表面的气孔数量和大小都逐渐减小,且剩磁比和矫顽力均逐渐增加;随着取向磁场强度的增加,厚膜样品中晶粒的分布具有各向异性,且剩磁比和矫顽力均随取向磁场强度的增加而逐渐增加。Barium ferrite （BaFe12Ol9） thick films were prepared by screen priming method. The effects of rolling time and intensity of alignment magnetic field on the microstructure and magnetic properties of the BaFe12019 thick films were investigated. The results show that with the increasing of the rolling time, the number and size of pores on the surface of the prepared BaFe12019 thick films decrease, while the remanence ratio and coercivity both increase gradually. As the intensity of alignment magnetic field increases, the crystal grain distribution of the prepared BaFe12O19 thick films is anisotropic, and meanwhile the remanence ratio and coercivity both increase.
