Boron Nitride Fiber Synthesis from Boric Oxide Precursors

  • Arthur E. Lindemanis
Part of the Materials Science Research book series (MSR, volume 17)


The effective application of boron nitride fibers as battery separators or as high modulus fibers requires improving the economics significantly, particularly in the conversion of B2O3 fibres to BN with ammonia. The kinetics were studied as a function of fiber diameter and temperature and found to fit a shrinking core model. Low melting point surface phases and a high temperature B-O-N phase also influence the bulk fiber nit riding process.
