| Abstract: | The major aspects of the theoretical study on use of polysilsesquioxanes as precursors to silicon oxy carbide ceramics through pyrolysis at elevated temperatures in inert atmospheres and a variety of applications, including matrices, infiltrates and coatings in ceramic matrix composites, were reviewed in this paper. Several methods of pyrolysis have been mentioned. The conversion of silsesquioxanes to silicon oxy carbide ceramics, the pyrolysis mechanism and the final products were discussed. Its coming developments are given. |
