Abstract

In this study, the synthesis and characterization of
potassium borate were studied using KCl, NaOH and H₃BO₃ asthe 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 KB₅O₈4H₂O (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.
