Cross‐linking of 1, formation of a SiC network, and reduction of the encapsulated TiO 2 particles are the three steps in the reaction of poly[(dimethylsilylene)diacetylene] ( 1 ) and TiO 2 which produces SiCTiC ceramics [Eq. (a)]. The reduction of the metal oxide in this case is possible at much lower temperatures than with carbon alone. This method can be applied to a number of metal oxides, and also B 2 O 3 . The ceramic's composition can be modulated by variation of the polymer.
