New Catalytic Routes to Preceramic Polymers: Ceramic Precursors to Silicon Nitride and Silicon-Carbide Nitride

Abstract

Pyrolysis of a set of silicon and nitrogen substituted polysilazanes are conducted under a set of standard conditions (5 degrees C/min to 900 degrees C in a nitrogen atmosphere). The apparent ceramic compositions and ceramic yields for pyrolyzed samples of the polysilazanes (Ph(H)SiNH)x, (C6H13(H)SiNH)x, (Me(H)SiNH)x, and (H2SiNMe)x are determined. Preliminary conclusions concerning structure/reactivity relationships are discussed based on the pyrolysis results. Keywords: Polysilazanes, Structure/reactivity relationships, Catalysis, Synthesis, Pyrolysis, New catalytic reactions. Reprints.
