The effects of adding silicon dioxide (SiO₂) nanowires on the properties of barium titanate (BaTiO₃) were investigated. The structure, morphology and optical properties were examined using X-ray powder diffraction (XRD), Fourier transform-infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and ultraviolet–visible diffuse reflectance spectrophotometry (DR). All of the prepared samples crystallized with a cubic BaTiO₃ structure. When the SiO₂ content was <2.0 wt%, no secondary phase was observed and the (BaTiO₃)_1–x/(SiO₂)_x samples exhibited a microstructure with small grains. However, Ba₂TiSi₂O₈ was detected upon further increasing the SiO₂ content. When compared to the pure BaTiO₃ sample, a slight increase in the $E_g$ value was observed for the (BaTiO₃)_1–x/(SiO₂)_x composites. The dielectric and electrical measurements were used to analyze the dielectric constant (ε′), dissipation factor (tan(δ)), conductivity (σ_ac) and impedance (Z). The results demonstrate that the addition of SiO₂ nanowires affects the properties of BaTiO₃. The study highlights the importance of SiO₂ nanowires in BaTiO₃ for use in microwave device applications.

研究了添加二氧化硅（SiO ₂）纳米线对钛酸钡（BaTiO ₃）性能的影响。使用X射线粉末衍射（XRD），傅里叶变换红外光谱（FTIR），扫描电子显微镜（SEM）和紫外可见漫反射分光光度法（DR）检查了结构，形态和光学性质。所有制备的样品均具有立方BaTiO ₃结构结晶。当SiO ₂含量＜2.0 wt％时，未观察到第二相，并且（BaTiO ₃）_1-x /（SiO ₂）_x样品表现出具有小晶粒的微观结构。但是，Ba ₂ TiSi进一步增加SiO ₂含量时，检测到₂ O ₈。与纯BaTiO ₃样品相比，$E_G$对（BaTiO ₃）_1-x /（SiO ₂）_x复合材料观察到该值。介电和电测量来分析介电常数（ε' ），损耗因子（TAN（δ）），电导率（σ _AC）和阻抗（Ž）。结果表明，SiO ₂纳米线的加入会影响BaTiO ₃的性能。该研究强调了BaTiO ₃中SiO ₂纳米线在微波设备应用中的重要性。
