Boron nitride (BN) nanostructures are chemically inert, electrically insulating, and potentially important in mechanical applications. Using borazine (B₃N₃H₆) gas as chemical precursor and the Chemical Vapor Deposition (CVD) BN nanostructures were obtained at a rate of 80.5 g/h, with sizes ranging between 20 and 50 nm. Their structure, morphology and chemical composition were analyzed by: X-ray, TEM, EDS, FT-IR, EELS and XPS. Taken altogether, the results obtained show that all the nanostructured material is stoichiometric BN with hexagonal and rhombohedral structure.
