| 英文摘要 | Durra was firstly transformed into carbon template by high-temperature pyrolysis and then converted into biomorphic sic by infiltration of liquid si in ar atmosphere at 1600 degrees c. the purified sic sample was characterized by x-ray diffraction, scanning electron microscope and mercury intrusion. the results suggest that the sample mainly consist of beta-sic and perfectly replicate the microstructure and morphology of the carbon template. the durra-derived sic has a mean pore diameter of 91.4 mu m and porosity of 76.6%, and both of them are similar to those of the carbon template, 88.5 mu m and 71.2%, respectively. the specific surface area of sic is 33.7m(2)/g, which is less than that of the carbon template, 59.4m(2)/g. the surface fractal dimension is 2.73 for the sic sample and 2.70 for the template by analyzing the mercury intrusion data. the durra-derived sic has characteristics of large grain size and high porosity. |
