According to the present invention, when manufacturing expanded graphite, it is possible to remarkably reduce the generation of waste and economically manufacture expanded graphite having a low content of volatile substances and good appearance, and thus, it is possible to efficiently manufacture a heat dissipation sheet having excellent thermal conductivity. Selon la présente invention, lors de la fabrication de graphite expansé, il est possible de réduire remarquablement la génération de déchets et de fabriquer économiquement du graphite expansé ayant une faible teneur en substances volatiles et un bon aspect, et ainsi, il est possible de fabriquer efficacement une feuille de dissipation de chaleur ayant une excellente conductivité thermique. 본 발명에 따르면, 팽창 흑연 제조시 폐산, 폐기물의 발생을 현저히 감소시킬 수 있고, 휘발성 물질의 함량이 낮고 외관이 양호한 팽창 흑연을 경제적으로 제조할 수 있으며, 따라서 열전도율이 우수한 방열 시트를 효율적으로 제조할 수 있다.
