A series of W-type hexagonal ferrites with the composition Ba1-xSrxFe22+Fe163+O27 (0 <= x <= 1) were prepared by the ceramic process in a reducing atmosphere during the whole process of pre-sintering and sintering. The phase composition, micro-morphology, and magnetic properties of the particles were investigated by XRD, SEM, and VSM. The results of XRD show that the single phase was observed in the W-type ferrites with different Sr content. The micro-morphology of the particles exhibits the uniform plane hexagonal structures of W-type ferrites with different Sr content. The coercivity (H-C) of the particles increases with the increase of Sr content (x), while the saturation magnetization (M-s) of the particles first decreases with x from 0 to 0.2, and then begins to increase when x continues to increase.
