Abstract: In this study by using the precursors of Zn5(CO3)2·(OH)6 and H3BO3, Zn3B6O12·3.5H2O type of a zinc borate compound is synthesised. A green sonochemical method of ultrasonic irradiation is used with several parameters such as; reaction temperature and reaction time. Synthesized zinc borate compounds are characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR) and Raman spectroscopy techniques. Then the surface morphologies are investigated by scanning electron microscopy (SEM). From the XRD results, the minimum reaction conditions to successfully synthesize Zn3B6O12·3.5H2O were found as 80°C – 50 min, 85°C – 40 min, 90°C – 40 min. The FT-IR and Raman spectroscopies showed that the synthesized products characteristic bands were in good agreement with the bands of boron compounds. SEM morphological analyses showed that synthesized compounds were in particularly thorn like and tubular with the particle sizes between 77– 296 nm. Also the reaction yields were calculated between 90.34– 97.12%.
