多元醇还原法制备Co-Ni和Fe-Co-Ni磁粉

Co-Ni and Fe-Co-Ni Fine Particles Prepared by the Polyol Process

通过多元醇还原法可以制得尺寸范围从几微米到几十纳米的球形、单分散和Co-Ni系和Fe-Co-Ni系磁粉,并在2～18GHz频率范围内研究其微波磁特性。实验表明,此法制得的Co-Ni系和Fe-Co-Ni系磁粉的物理化学特性随着Co含量的不同而呈现出一定规律性变化。

Spherical and monodisperse Co Ni and Fe Co Ni systems magnetic particles were synthesized by the polyol process over a wide size range lying from a few micrometers to a few tens of nanometers,and the microwave magnetic properties of them were investigated in the 2-18 GHz frequency range.From the result,it was found that the physico-chemical characterizations of the particles were varied with the different contents of Co.
