| 英文摘要 | The mixed surfactants were successfully applied to fabricate the highly porous Si3N4 ceramic foams by the direct foaming method. The oppositely charged surfactants mixed in slurries could combined into catanionic surfactant by the electrostatic attraction and facilitate the formation of ultra-stable foams. The microstructure of the Si3N4 ceramic foams, including pore structure, mean pore size, pore size distribution and porosity were tailored by varying the mixing ratio of surfactant, mixed surfactants concentration and solid content of the initial slurries. Si3N4 ceramic foams with porosity of 92%-97%, mean pore size of 140-240 mu m and compressive strength of 0.85-5.38 MPa were obtained by adjusting mixed surfactants between 0.1 and 0.4 wt% and solid content between 22 and 30 vol%. The compressive strength of Si3N4 ceramic foams in current work was much higher than most reported results. |
