In this study, hexagonal boron nitride (hBN) was synthesized with the modified O’Connor method in the presence of different additives. Structural properties of the synthesized materials were determined by X-Ray Diffraction, (XRD), Fourier Transform Infrared Spectroscopy, (FTIR), and Scanning Electron Microscopy (SEM). It was found that improving the precursor using different additives played a positive role by lowering the formation temperature. The average grain sizes (21–24 nm) and graphitization index (2.44–3.45) of hBN samples were calculated from the XRD pattern.
