摘要
Abstract
W-type ferrite Ba(Zn_(1-x)Ni_x)_2Fe_(16)O_(27) powders were prepared by solid phase ball-milling method. X-ray diffraction (XRD) and scan electron microscope (SEM) were used to study their phase composition and morphology. Microwave network analyzer was used to analyze electromagnetic properties of W-type ferrites and the influence of Ni-doped amount. It is found that powders are formed into W-type ferrite phase and formed fuller plane hexagonal flake structure at 1 300 ℃. From 2 to 18 GHz, the values of ε', μ' and μ" for W-type ferrites increase with the increase of Ni-doped amount and the magnetic loss gets to the highest value when x = 1.0 (Ni-doped amount).关键词
