Boron nitride microtubes (BNMTs) are successfully synthesized via a simple technique at 1200 °C. The method and logics used in the present study are relatively different and easy in comparison to previously synthesized boron nitride nanotubes, boron nitride microtubes and boron-carbon-nitride microtubes regarding the choice of precursors, experimental set up and reaction atmosphere. Field emission scanning electron microscopy (FESEM) shows a unique pipe-like morphology of the as-synthesized BNMTs with thin wall structure and larger internal space. X-ray photoelectron spectroscopy (XPS) survey shows B 1s and N 1s peaks at 190.8 eV and 398.5 eV that represent hexagonal boron nitride (h-BN) composition of synthesized microtubes. Raman spectroscopy demonstrates a peak at 1372.53 (cm–1) that corresponds to E 2g mode of h-BN.
