Abstract (en)
[origin: DE19806044A1] The invention relates to a method for producing crack-free Si/C/N-based moulded ceramic bodies by hot press moulding of cross-linked polysilazane powder and subsequent pyrolysis of the moulded body obtained by hot press moulding. The press temperature is higher than the maximum temperature in the TMA diagram of the optimally cross-linked polymer.
