【Abstract】 Ultrafine W-type ferrite powders were prepared by citrate combustion method,and their microstructures and magnetic properties were measured by XRD,TEM and VSM. The results indicate that properties of ferrite powders calcined at 1100℃are different from those of ferrite powders obtained by other methods. Experiments also show that the amount of citric acid can affect microstructures and magnetic properties of ferrite powders.更多还原
