Figure 8

Al Kα excited XPS normal emission spectra of boron (a), nitrogen (b), carbon (c), and silicon 1s (d) core levels from the SiC(N)/BN nanocomposites, respectively. Intensities of different core levels are too tantamount to scale with arbitrary offsets. (e) XRD patterns of SiC(N)/BN nanocomposite. (f) Raman spectra of the SiCN/BN nanocomposite after the thermolysis process under Ar atmosphere at 1600 °C.
