| abstract |
The invention relates to new polysilazanes, their production, their further processing to silicon nitride-containing ceramic material, and this material itself. To produce the polysilazanes, dialkylaminoorganyldichlorosilanes of the formula RSiClâ‚‚-NR'R 'are reacted with ammonia. The polysilazanes can then be pyrolyzed to ceramic material containing silicon nitride. The polysilazanes according to the invention dissolve in the usual aprotic solvents. |
