Abstract

The pyrolysis of Ti metal filled poly(siloxane) preceramic polymers heated at 1350°C in N2, Ar, and NH3, was evaluated in tees of the effect of pyrolysis atmosphere on the chemistry of the Ti transformation product. In NH3, the Ti particles react with the atmosphere to form newly stoichiometric TiN. In Ar, the Ti particles react with either gaseous hydrocarbon, i.e., methane, or carbon pyrolysis products of the poly(siloxane), to form non-stoichiometric TiC. Finally, in N2, the Ti particles react with carbon species from the poly(siloxane) and the nitrogen atmosphere, to form a TiC/TiN solid solution.
