摘要

For the preparation of the self-healing phase BxC with BC 3-CH4-H2 precursors, the production has been examined as a function of the initial gas ratios of BCl3(BCl 3+CH4) and H2(BCl3+CH4) at given temperature and pressure. The results show that the composition of the condensed phase is quite sensitive to the molar ratio of BCl 3(BCl3+CH4) and H2(BCl 3+CH4). The ideal condition for the deposition of B xC is that the ratio of BCl3(BCl3+CH 4) is 0.8 and the H2(BCl3+CH4) ratio ranges from 10 to 105.2. The carbon or boron-rich material is mainly controlled by the ratios of BCl3(BCl3+CH4) and H2(BCl3+CH4). The deposition condition of carbon-rich phase should be in low BCl3(BCl3+CH 4) (0.0∼0.8) and H2(BCl3+CH4) (10-2<102) ratios, whereas that of the boron-rich phase needs high BCl3(BCl3+CH4) (0.8∼1.0) and H2(BCl3+CH4) (104∼10 5) ratios.
