Beschreibung
Zusammenfassung:	Disclosed is a method of preparing a graphite bulk by coating graphite powder with binder, which includes steps of: (A) mixing graphite powder and a solvent containing a binder into a graphite mixed solution; (B) performing a first heating process on the graphite mixed solution so as to remove solvent; (C) performing a crushing process so as to obtain graphite powder containing the binder; (D) performing a cold forming process, cold isostatic pressing and a second heating process on the graphite powder containing the binder, thereby producing an artificial graphite powder. Accordingly, a graphite bulk with high strength can be prepared by coating a thin-layered binder on the surface of graphite powder.
