従来、黒鉛の特性は気孔率で予測してきたが、黒鉛特性のばらつきをより少なくし、高精度で予測するためには、さらに小さな因子をパラメータとして黒鉛特性を予測する必要がある。そこで、黒鉛に含まれる開気孔と閉気孔に着目し、2次元画像及び3次元画像を用いて黒鉛の気孔分布を解析し、黒鉛の熱特性を予測する手法を開発した。本研究では、気孔分布の解析結果及びそれに基づき作成した予測式により求めた熱伝導率の値と実験結果を比較した結果を報告する。

The characteristics of graphite have been characterized as a function of porosity. In order to further reduce the characteristic variation and to characterize them with high accuracy, it is necessary to characterize them as a function of some detailed factors. Therefore, we focused on the open and closed pore of graphite and analyzed them based on two and three dimensional images to develop the prediction method for thermal conductivity of graphite. In the present study, it was reported analytical results of pore distribution and comparison result of predicted thermal conductivity to the experimental one.
