▎ 摘  要

NOVELTY - Carbon powder electrifying to prepare graphene needs to use high temperature vacuum reactor, wherein the reaction temperature is up to 2700 degrees centigrade, and the highest use temperature of the plastic sealing ring is about 200 degrees centigrade. The invention claims a high temperature vacuum reactor for preparing graphene by electrifying carbon powder, wherein the positive and negative two electrode rods are inserted into the reaction tube, the reaction area in the middle of the reaction tube is placed with carbon powder, the sealing area at two ends of the reaction tube is sealed by electrode rod through sealing ring, By simultaneously increasing the inner diameter of the reaction tube and the outer diameter of the electrode rod of the sealing region of the sealing ring, the sealing ring is far away from the high temperature region and efficiently radiating, so as to realize the miniaturization of the high temperature vacuum reactor.
