Enhanced electrical and energy storage properties of BNT-based ceramics by the nanocrystals-induced method.

บทคัดย่อ ( Abstract )

The effect of BT nanocrystals on phase structure and electrical characteristics of lead-free BNT ceramics was investigated in this study. The molten-salt method was used to make the BT nanocrystals. All ceramics showed a pure perovskite phase. The density values ranged from 5.87 to 5.91 g/cm3. The highest density value was obtained for the sample of BT seed = 5 mol%. With increasing BT seed content, the dielectric constant (er) at room temperature tended to increase. The sample of 10BTs (x = 10 mol%) had the highest dielectric constant (er= 1652). For compositions of BT-added, the dielectric spectra showed a broad maximum around TF–R. The sample of 5BTs (x = 5 mol%) had the highest d33 value of 161 pC/N. Furthermore, a high energy storage density (W * 0.69 J/cm3) with the highest energy storage efficiency (g = 70%) was obtained from the sample of BT nanocrystals added (BTs = 0.10 mol%).
