The effects of processing parameters, such as ball milling time [6,25,26], thermal cycle [10] and sintering atmosphere [27], on the microstructure and dielectric properties of BaTiO3 systems have also been investigated in relation to the variation of the core/shell volumetric ratio. Wang et al. [26] reported that in a
Ball Milling Of Batio3 Henan Heavy Machinery. Mechanical activation of a mixture of polycrystalline powders Fe3O4 (50% wt.) and BaTiO3 (50% wt.) was performed in a planetary ball-mill, with different milling times (3 h, 6 h and 12 h). Average crystallite size determined by XRD analysis ranges from 12 to 30 nm, depending on the milling time.
ball milling, the grinding bowl, straddling on a turning support frame, also revolve about its axis. These two rotations form forces that are exerted on the milling balls and materials inside the bowl. These forces cause reduction of particle size and induce microstrains at the same time (Nath et al. 2010). In the present paper, the nano ball ...
