Abstract :In this study, the synthesis and characterization of potassium borate were studied using KCl, NaOH and H 3 BO 3  as the starting materials. The effects of the boron precursor, reaction temperature and time on the structure of the synthesized potassium borate were investigated. X-ray diffraction (XRD) showed the synthesized sample was santite, which has the chemical formula KB 5 O 8 4H 2 O (Powder diffraction file number: 01-1072-1688). The XRD scores increased upon decreasing the reaction temperature and time. The characteristic band values observed for boron and oxygen were investigated using Fourier transform infrared (FT-IR) and Raman spectroscopy. The morphology of the synthesized samples was characterized using scanning electron microscopy (SEM). The samples were found to be on the micro-scale with particle sizes <2.54 µm. The reaction yields were in the range of 75.01–95.03% for Set-1 and 72.04–92.22% for Set-2.
