Abstract: A process for producing oxygen-free or low-oxygen shaped bodies of silicon carbide, particularly SiC fibers, by using chemically reactive polysilanes and/or polycarbosilanes as precursors. In accordance with the invention green fibers are stabilized preferably in the presence of reactive gases.

Abstract: Halogenated polycarbosilanes with uniform or mixed halogenation prepared from aryl-substituted, particularly phenyl-substituted polycarbosilanes by reaction with halogenating reagents under polar or ionic reaction conditions, optionally in the presence of a Lewis acid catalyst.

Abstract: Polycarbosilanes in which some of the silicon atoms have been replaced by a hetero element selected from boron, titanium, zirconium, hafnium, etc. The hetero elements are incorporated into the polycarbosilane skeleton in such a way that, like the silicon atoms, they are bonded to the other parts of the polycarbosilanes via hydrocarbon bridges, and the polycarbosilanes are free of hetero element-oxygen-silicon bonds.

Abstract: Polycarbosilanes having Si units which are linked by phenyl-substituted methylene bridges or by partially or completely fluorinated hydrocarbon bridges. These polycarbosilanes are obtained by a Grignard polycondensation reaction. If phenyl substituents are present on the silicon atoms of the polycarbosilanes, they may also optionally be exchanged for halogen atoms in additional halogenating reactions, so that polycarbosilanes can be prepared which are both fluorinated on the hydrocarbon bridges and halogenated (particularly fluorinated) on the silicon atoms.
