Paper Title:
Preparation and Electromagnetic Property of Hexagonal W-Type Ferrite Obtained by the Method of Coprecipitation with Flux
  Abstract

Hexagonal W-type ferrite BaZn0.6Co1.4Fe16O27 was prepared by the method of coprecipitation with flux. The formation, microstructure, element composition and phases were analyzed by TG-DTA, SEM, EDS and XRD. The micrograph showed that the ferrite grains appeared to be hexagonal schistose texture obviously and the dimension of the grains was about 10μm. The product powders were composed mainly of BaZn0.6Co1.4Fe16O27 and few other phases such as α-Fe2O3, M-type ferrite (BaFe12O19) and S-type ferrite (MeFe2O4, Me for Zn or Co) were also found in the product. Electromagnetic parameters and microwave absorption capability were measured by the microwave vector network analyzer. The results showed that the reflection loss (RL) of the sample came up to -10dB in the spectrum from 8GHz to 18GHz and -20dB in the spectrum from 9.5GHz to 16GHz.
