Popis:	The family of borazines [(SiCl3)NB(Cln(CH3)1–n]3 was synthesized and characterized by NMR and IR spectroscopy, as wellas by single crystal structure analysis. After cross-linking with methylamine, a soluble polymer was obtained that was transformed to anall-inorganic random network of nominal composition Si1.0B1.0N3.0C0.9O0.1 (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.
