| 摘要 |
The present invention relates to a method for manufacturing a bulk-type oxide-based nanoporous body, which comprises the steps of: preparing an oxide-based nanoporous powder; filling the oxide-based nanoporous powder in a mold and setting same in a chamber of a discharged plasma sintering device; reducing pressure by forming a vacuum in the chamber, and pressing the oxide-based nanoporous powder and applying a direct current pulse to raise the temperature to a sintering temperature targeted to be less than the melting temperature of the oxide-based nanoporous powder; pressing the oxide-based nanoporous powder at the sintering temperature and discharge plasma sintering the oxide-based nanoporous powder; and cooling the temperature of the chamber to obtain a sintered body, and to a bulk-type oxide-based nanoporous body manufactured by the method. According to the present invention, a bulk oxide-based nanoporous body that is not in powder form but is conglomerated may be obtained. |
