Fabrication of Porous Ceramics for Microorganism Carrier by Hydrothermal Reaction
Porous ceramics for microoganism carriers were prepared with amorphous alumina and pore formers by hydrothermal reaction, burn-out and wash-out method. Activated carbon with average size of 67,222, and 405 $mutextrm{m}$, organic polymer and inorganic salt were used as pore formers. Specimens were hydrothermally treated at 200$^{circ}C$ for 24 h, heat-treated at 650$^{circ}C$ for 5 h, and washed out at 80$^{circ}C$ for 48 h. The formation of crystalline phase, porosity, pore size distribution and compressive strength were measured. The specimen with activated carbon was transformed to boehmite phase, but organic polymer and inorganic salt inhibited the aquohydroxoy complex gel and crystalline formation. The porous ceramics for microoganism carriers using activated carbon as a pore formers was successfully prepared, which is composed of ${gamma}$-alumina phase with porosity of above 70 vol% and the compressive strength of 40 kgf/$textrm{cm}^2$.
Key words: Microorganism carrier, Amorphous alumine, Hydrothermal reaction, Pore former
