Effect of reaction temperature on structure of co-polyborosilizane as a precursor of Si-B-N ceramic fibers
关键字：SiBN; ceramic fiber; polymeric precursor; polycondensation
A novel kind of polymeric precursor to SiBN ceramic fiber was synthesized by polycondensation of tetramethylaminosilane ((CH3NH)4Si) and trimethylaminoborane ((CH3NH)3B) using different reaction temperatures. Structure changes were discussed by using ...
