Outline
Hexagonal boron carbonitrogen (h-BCN) crystal was synthesized from the mixture of boron powder and CNH compound prepared by pyrolysis of Melamine (C3H3N3) under high temperature (1 400~1 500 ℃) and high pressure (5.0~5.5 GPa). X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy were used to determine the product chemical composition and characterization. The results show that the product has composition of B0.18C0.66N0.16(near BC4N) and atomic-level hybrid. X-ray diffraction analysis indicates that the powder has hexagonal network structure. Scanning electron microscopy result suggests that h-BCN crystal morphology are mainly hexagonal flaky and the diameter is about 1 μm, thickness 200 nm.
