| dc.description.abstractEn | Oxidation tests have been performed on model Si-C-N-O filaments prepared from a new polycarbosilazane (PCSZ) precursor, according to a spinning-oxygen-curing-pyrolysis procedure. Thermogravimetric analyses have been run under a flowing atmosphere of dry oxygen (P=100 kPa) at 1000 < T < 1400 °C. The oxidation treatment results in the growth of a silica layer (passive oxidation regime) and simultaneously the release of carbon oxides and nitrogen, with an overall weight increase. At a given test temperature, the kinetics of growth of the silica scale obeys a parabolic law. The parabolic rate constant is thermally activated with an apparent activation energy of 170 kJ mol−1. The rate-limiting step is diffusion-controlled. The ex-PCSZ filaments exhibit a better oxidation resistance than the related Si-C-O fibres prepared from polycarbosilane precursors according to a similar procedure. | |
