The family of borazines [(SiCl₃)NB(Cl_n(CH₃)_1-n)]₃ has been synthesized and characterized by NMR and IR spectroscopy, as well as by single crystal structure analysis. After crosslinking with methylamine, a soluble polymer was obtained, which was transformed to an all-inorganic random network of nominal composition Si_1.0B_1.0N_3.0C_0.9O_0.1 (idealized SiBN₃C) at 1400 °C. With an on-set of weight loss at 1840 °C and a resistance against rapid oxidation in pure oxygen of up to 1300 °C, the new Si/B/N/C ceramic shows a high temperature performance similar to those of previously reported Si/B/N/C materials.
