METHOD FOR PRODUCING GRAPHITE MATERIAL HAVING HIGH THERMAL EXPANSION COEFFICIENT AND THE GRAPHITE MATERIAL
To provide a method for producing a graphite material having a high thermal expansion coefficient from a conventional artificial graphite without use of natural graphite as raw material.SOLUTION: A method for producing a graphite material having a high thermal expansion coefficient comprises applying a compressive load to a carbon material fired at 800°C to 1200°C in a temperature rising process from 2400°C to 3000°C for graphitization so as to cause plastic deformation.SELECTED DRAWING: Figure 2
【課題】 原料として天然黒鉛を使用せずとも、通常の人造黒鉛原料を使用して、高熱膨張係数を有する黒鉛材料を製造する方法を提供すること。【解決手段】 ８００℃から１２００℃で焼成した炭素材料を２４００℃から３０００℃まで昇温し黒鉛化するプロセス中に圧縮荷重を負荷して塑性変形させることを特徴とする高熱膨張係数を有する黒鉛材料の製造方法。【選択図】 図２
