Summary

Test pieces were uniaxially dry-pressed from formulations consisting of 20-30 wt% polysilazane preceramic material and SiC and Si3N4 ceramic powders. Thermal crosslinking/pyrolysis of the molded pieces at temperatures well below normal powder sintering temperatures produced fully ceramic composites consisting of fully dense, submicrometer size, crystalline ceramic particles embedded in a highly nanoporous, amorphous Si-N-C ceramic matrix material The mechanical and physical properties, and their relationship to the microstructure, of these materials are discussed.
