| 英文摘要 | Porous solid-state-sintered SiC (S-SiC) membrane supports were successfully fabricated by pressureless sintering at 2150 degrees C in argon, using fine and coarse graded SiC powders as the main starting material. There were uniformly distributed and fully interconnected pores in as-acquired S-SiC membrane supports, accompanied with similar apparent porosities for all of them. When increasing the size of coarse SiC powder, their average pore sizes were distinctly enlarged from similar to 1.6 mu m to similar to 2.3 mu m, which significantly enhanced their nitrogen permeability from 0.9 x 10(-13) m(2) to 2.6 x 10(-13) m(2). Moreover, S-SiC membrane supports possessed outstanding flexure strengths of 134.1 +/- 21.3 MPa at room temperature and 88.7 +/- 8.4 MPa at 1000 degrees C owing to strong interface bonding between SiC grains. Compared with the traditional SiO2-bonded and mullite-bonded SiC supports, S-SiC membrane supports presented their great superiority in high-temperature flexure strength as well as acid and alkali corrosion resistance, which permitted them to be potentially applied in high-temperature and strongly corrosive environments. |
