The family of borazines [(SiCl 3 )NB(Cl n (CH 3 ) 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 Si 1.0 B 1.0 N 3.0 C 0.9 O 0.1 (idealized SiBN 3 C) 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.
