CONTAINER FOR PREPARING GRAPHITE SHEET

摘要

The present invention relates to a container capable of being divided by two or more to apply side pressure and effectively manufacture a graphite sheet; a firing furnace to manufacture the graphite sheet comprising the container; and a method of manufacturing the graphite sheet using the container. Effectively applying pressure to the raw materials; a crucible in accordance with the present invention can be used to manufacture graphite from the raw materials at high efficiency. Also, since the crucible of the present invention can be used to perform shrinkage through heat treatment by induction heating and/or graphitization, heating efficiency is improved and a graphitization temperature can dramatically be reduced when compared to an existing method which considerably decreases process expenditure. In addition, the present invention allows fast operation, precise temperature control, and various designs of firing furnaces; and is excellent in resistance to contaminants and is environmentally friendly.
