In this work, Solid solutions of BNT and barium titanate [(1-x) BNT + x BTO with x=0.00, 0.06, 1.00] have been prepared via conventional solid state route by using the planetary ball mill method. Crystallinity of the samples characterized by XRD and various structural parameters are calculated by employing Rietveld refinement technique.
It was found that the suitable poling condition for the BNT prepared by attrition milling was 55 kV/cm, lower than the BNT prepared by ball milling. At the applied electric field of 55 kV/cm, the BNT samples prepared by attrition milling process exhibited a dielectric constant of 437, a d 33 value of 107 pC/N and a k t value of 42%.
Among them, a planetary ball mill has been the most popular type of mill adopted in mechanochemical studies of oxides, as is characterized by higher milling energy and thus more efficient in reducing the particle size of initially larger particles 27,28, compared to vibratory and attrition mills.

nylon ball mill using ethanol as liquid medium. Single perovskite phases were obtained by heating the mixtures at 850 °C for 2 h. Ceramic samples were prepared by natural sintering of uniaxially pressed (100 MPa) pellets at 1135 to 1200 °C for 2 h depending on the composition; the pure BNT samples were sintered at 1100 °C for 2 h.
Scanning electron micrographs of BNT powders obtained via vibro-mill and conventional ball-mill techniques, calcined at 700 °C for 1 h are shown in Fig. 2. The average particle size of BNT powders estimated from both SEM micrographs were almost the same (0.2–0.4 μm). However, our results are comparable to that of Pookmanee et al.
