Silicon carbide precursors and their preparation and use |
摘要 |
(Dichloromethyl)methyldichlorosilane is reacted in the presence of Mg, K, Na or Li to form chloropolycarbosilanes which in turn can be reacted with a reducing agent to form polycarbosilane polymers that have utility as precursors to silicon carbide ceramics.
