摘要：
A process for producing crack-free shaped ceramic bodies based on Si/C/N by hot pressing of crosslinked polysilazane powder and subsequent pyrolysis of the hot-pressed shaped body employs a pressing temperature higher than the temperature maximum of the TMA curve of the optimally crosslinked polymer.
