▎ 摘　　要

NOVELTY - The crucible has a crucible case (1,3), a crucible cover (2), and an insert plate (3). The crucible case includes a chamber. When the crucible case includes one chamber, a partition (4) is placed on one side of the crucible case. When the crucible case includes multiple chambers, the insert plate is placed in the crucible case, and the crucible case is divided into multiple chambers by the insert plate. USE - Graphite crucible for a graphitizing furnace i.e. Ichson furnace, used for powder cathode material processing for preparing graphene heat-conducting film. ADVANTAGE - The graphite crucible has simple structure, convenient loading and unloading, and can be used for mass production. The crucible solves the problem of preparation of large scale of graphite film, and improves the product performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a graphene thermally conductive film by using the graphite crucible for a graphitization furnace. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic plan view of a graphite crucible for a graphitization furnace. Crucible case (1) Crucible cover (2) Insert plate (3) Partition (4)
