In this study, lead oxide (PbO) nanostructures are fabricated by an ultrasound-assisted sonochemical method, and re-ultrasonic effects on them are investigated. In the synthesis process, lead nitrate powder is used as a precursor, and potassium hydroxide serves as a precipitation agent. The resulting samples are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and Fourier transform-infrared spectroscopy (FT-IR). Re-ultrasound is also performed to terminate the growth of the PbO nanorods, stabilize them, and preserve their morphology. According to the XRD results, the re-ultrasonic effect did not change the crystal phases, and the tetragonal and orthorhombic crystal phases were preserved. The effect of the calcination time was investigated too; an increase in it led to a decrease in the irregular nanorods size but an increase in the crystallite size.

在这项研究中，氧化铅 (PbO) 纳米结构是通过超声辅助声化学方法制造的，并研究了再超声对它们的影响。在合成过程中，以硝酸铅粉为前驱体，氢氧化钾为沉淀剂。所得样品通过扫描电子显微镜 (SEM)、X 射线衍射 (XRD)、能量色散 X 射线光谱 (EDX) 和傅里叶变换红外光谱 (FT-IR) 进行表征。还进行再超声以终止 PbO 纳米棒的生长，稳定它们并保持其形态。根据XRD结果，再超声效应没有改变晶相，保留了四方晶和正交晶相。还研究了煅烧时间的影响；
