The characterization results of hollow ceramic beads show that oxidant KClO 3 had a great influence on the preparation of hollow ceramic beads. The morphology picture and XRD analysis showed that the surface of hollow beads without KClO 3 was smooth, and the particle size analysis results show that the particle size was 10 ~ 50μm. Without KClO 3 , the average particle size is 28.08 μm; After adding KClO 3 , dense dendritic crystal structure was distributed on the surface of hollow beads, and the phase is mainly BaFe 2 O 4 , and the distribution range of hollow beads is 5 ~ 40 μm, and the average particle size is 16.02 μm ° It could be inferred from the analysis that the quenching reaction is fully carried out after the addition of KClO 3 , resulting in a large amount of gas, reducing the volume of ceramic droplets and reducing the particle size of hollow beads.
