Abstract

Plate-like Zn₂W barium hexagonal ferrites were prepared using a combined coprecipitation and molten salt method. The thermal decomposition behavior of precipitates was systematically studied by TG-DSC and XRD. Pure plate-like Zn₂W barium hexagonal ferrites with optimal properties were obtained at a synthesis temperature of 1150 °C for 1 h. Phase composition, morphology and magnetic properties of the Zn₂W ferrite powders synthesized at different temperatures (1100-1250 °C) and different holding times (0.5-3 h) were investigated by XRD, SEM and VSM. The electromagnetic parameters were studied by VNA. Saturation magnetization of Zn₂W ferrite synthesized at 1150 °C for 1 h reached the maximum of 76.24 emu/g, whereas coercivity decreased with the increase in synthesis temperature and holding time.
