Abstract
Official abstract text for this publication.
A preparation method for graphitized carbon material is disclosed. The method may include placing a water-cooled copper mold having a water-cooling equipment at a bottom thereof in a vacuum arc melting furnace, wherein the water-cooled copper mold has disposed thereon a graphite crucible with carbon material therein and the graphite crucible has a tungsten rod placed thereon, with a lower terminal of the tungsten rod and the carbon material within the graphite crucible aligning. The method may further include flowing a gas after placing the vacuum arc melting furnace in a vacuum environment before heating the vacuum arc melting furnace to at least 3200 degrees Celsius to graphitize the carbon material and to form a fully graphitized carbon material after cooling.
First claim
Opening claim text (preview).
What is claimed is: 1 . A graphitized carbon material preparation method, comprising: placing a water-cooled copper mold having a water-cooling equipment at a bottom thereof in a vacuum arc melting furnace, wherein the water-cooled copper mold has disposed thereon a graphite crucible with carbon material therein and the graphite crucible has a tungsten rod placed thereon, with a lower terminal of the tungsten rod and the carbon material within the graphite crucible aligning; and flowing a gas after placing the vacuum arc melting furnace in a vacuum environment, before heating the vacuum arc melting furnace to at least 3200 degrees Celsius to graphitize the carbon material and to form a fully graphitized carbon material after cooling. 2 . The preparation method according to claim 1 , wherein the gas flown into the vacuum environment is argon or helium. 3 . The preparation method according to claim 1 , wherein the lower terminal of the tungsten rod facing the graphite crucible is tip-shaped. 4 . The preparation method according to claim 1 , wherein the water-cooled copper mold is equipped with a recess in which the graphite crucible is placed.
