Crystalline boron nitride (BN) powders were prepared by combustion method using glycine as a fuel. Experiments were carried out by heating dehydrated borax (Na 2 B 4 O 7) with NaNO 2 , KNO 3, NH 4 NO 3 in N 2 atmosphere at 350 0 C and glycine was used as a fuel as well as a source for nitrogen. Borax was used as a boron source and nitrogen compounds (NaNO 2 , KNO 3, NH 4 NO 3) were used as the nitrogen source. The reactions were carried out in a tantalum autoclave having the provisions for the

The as prepared samples were systematically characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared spectroscopy (FTIR), UV-Visible spectroscopy (UV) and Photoluminescence spectroscopy (PL). The reaction has resulted in the form of hexagonal boron nitride with high purity and good yield.
