Boron-Nitride and Its Precursors.

reportActive / Technical Report | Accession Number: ADA194958 | Open PDF

Abstract:

Formation of preceramic polymers by stepwise pyrolysis of borazines was found to be strongly dependent upon the ring substituents. Boron nitride fibers were obtained via preceramic polymers produced from B-triaminio-N-tristrimethylsilylborazine. Studies were carried out to determine the suitability of linear boron-nitrogen composition as preceramic polymer precursors. The mechanisms responsible for the observed results are delineated.
