To investigate the effect of BaTiO 3 powders during ball milling on the structure, SEM and XRD were utilized. As shown by SEM in Fig. 2 a, the raw hBN platelets exhibit a large lateral size of approximately 30 μm and large thickness of about 2 μm. After directly ball milling for 8 h, the lateral size and thickness of asprepared BNNSs are both deduced (Fig. 2 b).

The effects of ballmilling condition on the formation of coreshell structure in BaTiO 3 grains were studied. As the ballmilling time increased from 12. h to 48 h, the stress given by the milling process was accumulated in the powders while the primary powder size was reduced at 24 h milling and additional comminution of powders occurred at 48 h milling.
