Zn2+取代W型钡钴铁氧体的制备及其电磁性能研究
Preparation and Electromagnetic Properties of Zn2+ Substituted W-type Ba-Co Ferrites
摘要
Abstract
The Zn2+ substituted W-type Ba-Co ferrites powder, BaZnxCo2-xFe16 O27 (x =0. 8, 1.0,1.2) was prepared by a sol-gel method. The powder was characterized by X-ray diffraction, scanning electron microscope, vibrating sample magnetometer and vector network analyzer. The influence of sintering temperature and Zn2* content on the crystal structure was studied o The particle appearance , magnetic properties and electromagnetic parameters of the sample with different Zn 2+ content were analyzed. The results show that the average grain size was about 25.06 -32.04nm, the particle size was about 3 - 9μm, well-distributed and regular shaped W-type Ba-Co ferrites powder with hexagonal flake structure was obtained by sol-gel method at 1300 ℃ . The maximum Ms reached to 105. 99 A · m · kg-1 when x = 1. 2. And the magnetic loss increased with the rising Zn2+ concentration in the range of 4 - 11 GHz, the value was 0.2 -0.8, while it decreased with the rising Zn2+ concentration in the range of 11 - 18GHz, the value was 0 -0.5.关键词
