Synthesis of hexagonal boron carbonitride phase by solvothermal method

Abstract A solvothermal reaction of CH 3 CN·BCl 3 and lithium nitride (Li 3 N) using benzene as the solvent has been successfully applied to prepare boron carbonitride at 300 °C and less than about 7 MPa. X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) are used to confirm their chemical composition and atomic-level hybrid. X-ray diffraction (XRD) and transmission electron diffraction (TED) analysis indicate that the powders have hexagonal network structures.
