Abstract:
1. A graphite base manufacturing method comprising the steps of: (a) grinding natural graphite into nanometered graphite powder; (b) mixing said nanometered graphite powder with a bonding agent to form a graphite mixture; (c) grinding said graphite mixture into ball-like graphite; (d) processing said ball-like graphite into a graphite mass with a high pressure by means of hot press, cold press or vibration; (e) dipping said graphite mass in a liquid phase asphalt, enabling said liquid phase asphalt to fill up crevices in said graphite mass; (f) graphitizing said graphite mass to a dry state graphite block; and (g) covering a top surface of said dry state graphite block with a layer of metal coating to form a graphite base.
