摘　　要：以氧化铁、氧化锌、氧化镍和氧化铜为原料,采用氧化物法制备NiCuZn铁氧体,研究了950℃下不同烧结时间对NiCuZn铁氧体的晶体结构、表面形貌、密度、磁导率、居里温度、温度稳定性、饱和磁感应强度,剩余磁感应强度、矫顽力及功率损耗的影响。结果表明,所有样品均为单一尖晶石相;随着烧结时间的延长,晶粒尺寸、密度、磁导率和饱和磁感应强度单调增大,居里温度几乎没有变化,剩余磁感应强度先增大后降低,矫顽力及功率损耗则单调降低。Using ferric, zinc, nickel and copper oxide as raw materials and sintering at 950℃ for different time, NiCuZn ferrite materials were prepared by oxide method. The effects of the sintering holding time were investigated on the crystal structure, surface morphology, density, permeability, Curie temperature, saturation magnetization, residual magnetic flux density, coercive force and power loss of the NiCuZn ferrite materials. It is indicated that all the samples are single spinel phase. The grain size, density, permeability and saturation magnetization of the NiCuZn ferrite materials increase with extending sintering holding time. The sintering time have no obvious effect on Curie temperature. With extending the holding time, residual magnetic flux density increase first and then decrease, both the coercive force and power loss of the materials decrease.
