NOVELTY - The utility model claims a graphene film preparation technology field, claims a graphene film preparation high temperature furnace, comprising: furnace body; a crucible, the crucible is installed in the furnace body, for containing material; a heating device, the heating device is installed in the furnace body and is set around the crucible; the heating device is used for heating the crucible and the material; a vacuum pump, a vacuum pump is set outside the furnace body and connected with the inner space of the furnace body through the pipeline, for vacuumizing the furnace body. The utility model claims a graphene film preparation high temperature furnace can connect the vacuum carbonization and graphitization process of the graphene raw film into a whole; there is no need to segment process, which not only can avoid the temperature reduction and graphitization of the segmented processing vacuum carbonization, but also can save the time of segment processing. introducing continuous vacuumizing in the carbonization stage; the oxygen-containing functional group and water in the graphene original film can be quickly decomposed and discharged; the graphene film is more compact; finally, the effect of the graphitized crystal is better; the heat-conducting performance is better.
