| abstract |
The invention relates to novel crosslinkable polysilazane compositions, which are characterized in that they comprise an effective amount of at least one silicon compound, substantially inert with respect to said polysilazanes, and capable of being transaminated by a compound. amine comprising at least one NH group. The compositions according to the invention are then crosslinked by bringing into contact with said amino compound. The compositions thus crosslinked can be used for the preparation of ceramic products based on SiC and / or Si3 N4. |
