Since the excellent microwave absorption properties and good cost鄄effectiveness, W鄄type barium fer鄄
rite has been extensively studied. This paper introduces the main preparation methods of BaMe2Fe16O27 and summari鄄
zes the current research status of using different elements as Me and rare earth ions doped W鄄type barium ferrite. And
the research direction of W鄄type barium ferrite in the future is described.
