マイクロウェーブ照射による膨張黒鉛の生成

Abstract

The pore structure inside the worm-like particles of exfoliated graphite prepared by microwave irradiation was studied by using image processing. The pore parameters, cross-sectional area and lengths of major and minor axes which were determined from about 17000 pores observed on the fractured surfaces of worm-like particles through image processing, were difficult to differentiate from those on the sample exfoliated by rapid heating to 1000℃. Irradiation of microwave for 60 s increased large size pores, but the average parameters showed no dependence on irradiation time. Possibility of microwave exfoliation technique for practical applicationsto exfoliated graphite production was discussed.
