| Abstract: | Polyborosilazane was synthesized by copolycondensation reaction using B(NHCH_3)_3 and Si(NHCH_3)_4 as micromolecular precursors and was spun into SiBN(C) ceramic fiber by melt spinning process.The effect of the ratio of micromolecular precursors on the structure of polyborosilazane was studied by infrared spectrometry,nuclear magnetic resonance spectrometry and elemental analysis.The results showed that polyborosilazane had the dominating functional groups of B—N six-membered ring, Si—N,Si—N—B and N—H.The melting spinning experiment showed that polyborosilazane had fairly good spinnability with Si (NHCH_3)_4 and B(NHCH_3)_3 volume ratio of 1:1.3,from which a continuously windable polyborosilazane fiber can be produced with smooth surface and the diameter of 50 - 60μm. |
