Abstract Scope In this study, an allylhydropolycarbosilane polymer precursor was used to synthesize SiC at 1200C, 2200C, and 2500C in an argon atmosphere. Detailed structural evolutions were investigated by experimental and analytical methods. The material is comprised of a Si-containing amorphous matrix phase and a free-carbon phase till 1200 oC. The amorphous matrix phase is comprised of SixCy [x+y=4; 0≤{x,y}≤4] and free carbon. With increasing pyrolysis temperature, the amorphous matrix becomes more ordered, accompanied by a transition among SixCy followed by formation of stoichiometric SiC and nanocrystalline graphite. At ultrahigh temperatures (>2200 oC), SiC undergoes a complete phase transformation from the amorphous to the crystalline phase. The current research on the phase and nanostructure of polymer derived SiC at ultrahigh temperatures can lead to a better understanding of its properties and potential applications.
