Abstract: 29Si and 13C MAS NMR methods have been applied to examine the products in the pyrolysis of several kinds of organic silicon polymers for preparing SiC ceramic.Their structures have been analysed by means of 29Si and 13C MAS NMR spectra.The results indicate that the SiC phase can be obtained from the pyrolysis of PC and PCO polymer precursors.
