The characterization of samples was done by Fourier transformation infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Lithium salts played a positive role by lowering the formation temperature. The average grain sizes (22-26 nm) and graphitization index (1.7-2.9) of h-BN samples were calculated from XRD pattern. TEM images illustrated that the products were needle-like and multi-layered nano-crystalline h-BN powders.eninfo:eu-repo/semantics/closedAccessHexagonal Boron NitrideNanocrystalline MaterialsO'Connor MethodCharacterizationArticle10.1016/j.ceramint.2018.04.139441113161131642-s2.0-85045836154Q1WOS:000436351700162Q1
