Abstract Recently, sonochemistry has been used for the synthesis of inorganic compounds, such as zinc borates. In this study using zinc sulphate heptahydrate (ZnSO4·7H2O) and boric acid (H3BO3) as starting materials, a zinc borate compound in the form of Zn3B6O12·3.5H2O was synthesized using an ultrasonic probe. Product’s characterization was carried out with using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and Raman spectroscopy. Zinc borate compound’s chemical bond structure was observed with Raman and FTIR. From the XRD results it was seen that Zn3B6O12·3.5H2O can be quickly synthesized upon heating at 80°C and 85°C (55 min) or 90°C (45 min) in very high yield (>90%). The minimum particle size obtained was ~143 μm from the SEM results. Zinc borate compound was synthesized at a lower temperature in less time than other synthesized zinc metal compound in literature.

使用声化学从硫酸锌中加速和有效合成硼酸锌

摘要 最近，声化学已被用于合成无机化合物，如硼酸锌。在本研究中，以七水硫酸锌 (ZnSO4·7H2O) 和硼酸 (H3BO3) 为起始原料，使用超声波探头合成了 Zn3B6O12·3.5H2O 形式的硼酸锌化合物。使用 X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、傅里叶变换红外光谱 (FT-IR) 和拉曼光谱对产品进行表征。硼酸锌化合物的化学键结构用拉曼光谱和红外光谱观察。从 XRD 结果可以看出，Zn3B6O12·3.5H2O 可以在 80°C 和 85°C（55 分钟）或 90°C（45 分钟）下以非常高的产率（>90%）快速合成。根据 SEM 结果，获得的最小粒径为 ~143 μm。
