摘要
介绍了一种应用于MHz下的高磁导率(μi=500)、高Q值(在1MHz下超过120)、低烧结温度(880℃)NiCuZn材料的开发。研究表明,引入适量的CuO并掺杂适量的V2O5和Co2O3可以促进晶粒的生长,从而降低烧结温度,并且可以获得高Q值;通过对原材料的选择,严格控制主配方和制备工艺获得了优良的材料性能。
This paper introduces the development of a kind of high permeability (μ i=500), high Q (beyond 120 measured at 1MHz), low sintering temperature (880℃) NiCuZn ferrite material ZL500. It is found that a proper amount of CuO addition contributes to the grain growth in the sintering process, leading to decrease in sintering temperatures. Meanwhile, addition of proper amount of V2O5 and Co2O3 is helpful to obtain high Q value. Excellent properties can be achieved by using high purity raw materials, strictly controlling the main prescription and production process.
