Preparation and Electromagnetic Property of Hexagonal W-Type Ferrite Obtained by the Sol-Gel Method

Abstract:

Hexagonal W-type ferrite BaZn_0.6Co_1.4Fe₁₆O₂₇ was prepared by the sol-gel method. The formation, microstructure, element composition and phases were analyzed by TG-DTA, SEM, EDS and XRD. The electromagnetic parameters and microwave absorption capability were measured by the microwave vector network analyzer. The results showed that the reflection loss of the ferrite BaZn_0.6Co_1.4Fe₁₆O₂₇ in the spectrum of 8-18GHz came up to -10dB and came up to -20dB in the spectrum of 9.5-16.4GHz.
