Boron nitride and its precursors. Technical report

OSTI ID:6775537
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-tris(trimethylsilyl)borazine. 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.
