Preparation and Electromagnetic Property of Hexagonal W-Type Ferrite Obtained by the Sol-Gel Method
Hexagonal W-type ferrite BaZn0.6Co1.4Fe16O27 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 BaZn0.6Co1.4Fe16O27 in the spectrum of 8-18GHz came up to -10dB and came up to -20dB in the spectrum of 9.5-16.4GHz.
