An easily prepared precursor from polymerization of trichloroborazine (B3N3H3Cl3) and aniline was selected as the starting material and N-methyl pyrrolidone (NMP) was used as the solvent to synthesize hexagonal BCN microspheres in bulk quantity via an improved electrospray method.This approach can control the diameter of the as-prepared spheres by manipulating the voltage of the electrospray apparatus.The product was characterized by scanning electron microscopy,energy dispersive spectroscopy,X-ray diffraction and X-ray photoelectron spectrometry.The results show that the fabricated BCN microspheres have smooth and concave surface characters with diameter ranging from 10 to 30 μm.The B∶C∶N atomic ratio is about 1∶1.12∶0.94.
