The present invention relates to novel alkylhalogensilylaminoboranes, particularly alkylchlorosilylaminoboranes, which enable the viscosity of polyborosilazane compounds to be adjusted by changing the number of reaction centers. The invention also relates to a structural feature R 1 —Si—NH—BR 2 wherein R 1 or R 2 or both are hydrocarbon radicals having 1 to 20 C atoms, in particular alkyl radicals, phenyl radicals or vinyl radicals. Borosilazane compounds, novel oligomeric or polyborosilazane compounds, silicon-boron carbonitride ceramic powders, ceramic materials based on SiC, SiN and BN and their respective production methods and polyborosilazanes and ceramic materials About use. |
