COMPACT DRYING METHOD
A compact is formed by introducing a slurry containing a ceramic powder or a metal powder, a binder and a solvent into a compaction die, and compacting the slurry in the compaction die. The compact embedded in the compaction die is immersed in an alternative CFC (liquid) (FIG. 4A). The solvent contained in the compact is gradually replaced with the alternative CFC. In the course of this process, the compact separates naturally from the compaction die (releasing is achieved) without receiving an external force. Subsequently, the compact is taken out of the alternative CFC (liquid). The alternative CFC has a boiling point as low as 95° C. at 1 atmospheric pressure. Accordingly, the alternative CFC contained in the compact will volatilize at high speed, thus being removed. Consequently, the compact can be dried in a relatively short time without being heated.
