Abstract: | SiBONC ceramic powders have been prepared via a polymer pyrolysis route using silicon tetrachloride (SiCl4), benzaldehyde (PhCHO), boron trichloride (BCl3) and aniline (PhNH2) as starting materials. Fourier transform infrared spectra (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and transmission electron microscopy (TEM) were performed to investigate the structural characteristics of the polymer precursor and the ceramic powders. The SiBONC ceramic powders in spherical shape with a mean diameter of 50 nm are amorphous and composed of B-N, Si-O, Si-C, and SiONx groups. The SiBONC ceramic powders were sintered at 1700 °C to a dense material which still remained amorphous. |
