摘要Hexagonal boron carbonitrogen (h-BCN) compound is synthesized from a mixture of boron powder and CNH compound prepared by pyrolysis of melamine (C3H6N6) under high temperature (1400--1500°C) and high pressure (5.0--5.5GPa). X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and Raman spectroscopy are used to determine the chemical composition and bonds of the product. The results show that the product has composition of B0.18C0.64N0.16 (near BC4N) and atomic-level hybrid. X-ray diffraction analysis indicates that the powder has a hexagonal network structure. Scanning and transmission electron microscopy results suggest that h-BCN compound morphology is mainly flaky in width about 1μm and thickness 200nm.
