Summary

The phase reactions, the crystallisation behaviour and the accompanied thermal degradation of two Si-C-N precursor ceramics, which were derived from polyvinylsilazane and polyhydridomethylsilazane respectively, were studied by means of thermodynamic calculation of phase diagrams, DTA/TG, XRD and SEM. The CALPHAD type simulations were confirmed by the experimental results. The thermal degradation of both ceramics have been characterised quantitatively by taking into account the endothermic phase reactions Si3N4+3C = 3SiC+2N2 and Si3N4 = 3Si+2N2.
