The Effect of The Reaction Conditions on The Synthesis and Characterization of Potassium Borate from Potassium Chloride

Abstract

In this study, the synthesis and characterization of potassium borate were studied using KCl, NaOH and H3BO3 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 KB5O84H2O (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
