Ba-ferrites Hollow Microspheres Prepared by Self-reactive Flame Spraying Method

摘要：

　　Barium ferrites hollow microspheres were prepared by self-propagating high-temperature synthesis self-reactive flame spraying method.The droplets enter in the cooling medium and solidified rapidly so that the gas can not escape to remain holes inside the products.The powder samples were used for characterization.The microstructure and crystal structure were studied by SEM,EDS and XRD.The results show that the obtained particles are hollow microspheres.They are spherical or ellipsoidal shapes from nanometer dimension to several micrometers.The phase structure of composite powders is the mixtures of barium ferrite and Fe2O3.
