Polyborosilazanes (PBSZs) were synthesized by co-ammonolysis of 2,4,6-trichloroborazine and dichloromethylsilane and used as precursors for SiBCN ceramics. The pyrolyzed products were characterized with Fourier transform infrared, X-ray photoeletron spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction, and scanning electron microscopy (SEM). The results indicated the content of B or Si plays an important role in controlling the high temperature behavior of the precursors. The resistance of the ceramics, which were obtained from pyrolysis of PBSZs at 1500°C, toward oxidative attack up to 1000°C was also investigated by TGA and SEM/EDX. © 2010 Wiley Periodicals, Inc.
