| description | In order to study high performance oriented porous ceramics for the fuel cells and other fields, ZrO2 porous ceramics scaffold are fabricated by using tape-casting and screen printing methods. ZrO2 green tapes are prepared by using tape-casting and then the graphite stripes which are screen-printed on the surface of dry green tapes. Then the green tapes with graphite stripe on them are laminated and thermal synthesized in a certain order. Then the graphite phase is burnt out through sintering. The analysis is on the pore structure of porous ceramics scaffold. The thermal shock resistance of porous ceramic has been tested. Results show that the pore size of porous ceramic is regular by this method, the pore density is large and parallel, and with the thickness of the ceramic layer is increasing, the edge becomes regular. The thermal shock resistance cycles (25 ~1000℃) of porous ceramics can be increased up to 47 times with the increase in the thickness of green tapes. |
