Bismuth titanate nanostructure, Bi₁₂TiO₂₀, (BTO) belonging to sillenite family was synthesized by chemical route at the sintering temperature 800 °C for a period of 6 h. The crystalline phase of the materials was investigated by the X-ray diffraction method. The morphology and particle size of the BTO sample were determined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis, respectively. The SEM images displayed the bimodal structure, and average grain size was found to be in the range of 0.6–3.7 µm. TEM observation confirmed the nanocrystalline nature of the particle having size of 50 ± 20 nm. The value of dielectric constant and dielectric loss for Bi₁₂TiO₂₀ ceramic was found to be 8.29 × 10³ and 3.27, respectively, at the temperature 468 K and frequency 100 Hz.

在800℃的烧结温度下，通过化学路线合成了钛酸铋纳米结构Bi ₁₂ TiO ₂₀（BTO）。通过X射线衍射法研究了材料的结晶相。分别通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）分析确定BTO样品的形貌和粒径。SEM图像显示双峰结构，平均晶粒尺寸在0.6-3.7 µm的范围内。TEM观察证实尺寸为50±20nm的颗粒的纳米晶体性质。发现Bi ₁₂ TiO ₂₀陶瓷的介电常数和介电损耗值为8.29×10^图3和3.27分别在温度468 K和频率100 Hz下显示。
