Feb 01, 2007· 3 – 3 (BF–PT) powders were synthesized from a mixture of the oxides Bi 2 O 3, Fe 2 O 3, PbO and TiO 2 using a Fritsch P4™ varioplanetary ball milling system. The perovskite structure of the BF–PT powder can be obtained well and the crystallite size of the powders was greatly reduced to 20–35 nm after milling for 8 h.
The perovskite layers are composed of m layers of TiO6 octahedra and bismuthoxide layers that are alternately stacked in the crystal structure. It is ... Mechanical activation was performed in air atmosphere in a planetary ball mill (Fritch Pulverisette 5) for different milling times: 1, 3, 6 and 12 h. Milling conditions were the
After ballmilling in water, the calcined powder of composition A which has pure perovskite phase (Fig. 1) was changed to a combination of perovskite BaPbO3, BaCO3 and PbO2 as shown in Fig. 6(a). The decomposition of BaPbO3 results in the high resistivity of the corresponding sintered specimens. In addition, the resulting PbO2 phase Fig. 6.
