| Abstract: | Tubular porous ceramics with more than 40% open porosity and about 6 μm mean pore size were fabricated from natural zeolite powder with starch as pore-forming agent. The optimized processing parameter was 1100–1150 °C with a holding time of 1 h. Permeability of nitrogen and water flux of the tubular specimens was measured and discussed, and the obtained optimized values are 2480 m3m−2 h−1bar−1 and 26 m3m−2 h−1 bar−1, respectively. |
