 note = {シアセル法は液体拡散測定実験法の1つで、加熱冷却過程がないこと、凝固過程が測定に影響しないことが特徴である。しかしこの手法は試料の蒸発を防止する必要が有り、GaAsのような高蒸気圧液体の拡散係数の測定は困難である。本研究では、高蒸気圧物質の液体拡散測定用にシアセル法のシーリング技法を開発した。始めに、シーリング機構を研究する実験を行った。シーリング用に酸化ほう素の有効性を確認し、窒化ほう素るつぼを通過する試料蒸気の透過性を調査する実験を行った。続いて、シーリング機構を持ったシアセルを製作し、拡散実験を行った。酸化ほう素は高蒸気圧試料の蒸発防止に有効であること、試料は非透過性の窒化ほう素を通っても出てくることを確認した。, The shear cell method is one of the experimental methods of liquid diffusion measurements, which has the following advantages; heating and cooling process aren't included for measurements, and solidification process doesn't affect on measurements. But shear cell method needs to prevent the evaporation of sample, and it is hard to measure the diffusion coefficients of high vapor pressure liquids, such as GaAs. In this research, a sealing technique of the shear cell method was developed for liquid diffusion measurements of high vapor pressure materials. First, the investigation to confirm the sealing mechanism was performed. Then the effectiveness of B2O3 for sealing was confirmed, and the experiments were carried out to check the transmissivity of sample through a boron nitride crucible. A shear cell with sealing mechanism was produced, and a diffusion experiment was performed. It was confirmed that B2O3 was effective to prevent high vapor pressure sample from evaporation., 資料番号: AA0029039016, レポート番号: NASDA-TMR-000013E},
