POLYMERIC HYDRIDOSILAZANES AND PROCESSES FOR THEIR PREPARATION, AND THEIR USE |
| 摘要 |
The invention relates to novel polymeric hydridosilazanes, processes for their preparation and their use for the preparation of ceramic material containing silicon nitride. To prepare the polymeric hydridosilazanes, polymeric hydridochlorosilazanes are reacted with NH3. To prepare the ceramic material containing silicon nitride, the polymeric hydridosilazanes are then pyrolysed.
