  • functional materials;
  • pyrolytic transformation of preceramic polymers to CMC-s (ceramic matrix composites);
  • pyrolysis


The processes during the pyrolytic transformation of the preceramic polymers to CMC-s (ceramic matrix composites) with Si3N4/SiC/residual C or SiC/SiO2/residual C are presented. The thermal decomposition (pyrolysis) up to 1100 °C in Ar/N atmosphere produces an amorphous ceramic with a good resistance against oxidation. Thus, the transformation of the organo-metallic polymers into an amorphous matrix is influenced by the atmosphere of the reaction (Ar, N). The pyrolytic transformation is accompanied by the loss of volatile, resulting high-density differences between the precursors (<1 g/cm3) and the ceramic residuum (<2.5 – 3.2 g/cm3). The residual porosity and the contraction (<70-80 %) are very high. Four types of preceramic polymers with Si have been used. The pyrolysis at 1200, 1400 and 1600 °C produced the experimental CMC-s. The microstructure analysis has evidenced the SiO2 and SiC phases. With the same precursors but in N atmosphere and pyrolysis between 1200-1400 °C CMC-s with Si3N4/SiC/residual C matrix have been obtained.
