Research Abstract

1. 本年度、設備備品として、精密イオンポリッシングシステム(PIPS691)・PIPSコールドステージ・GATAN636試料冷却2軸傾斜ホルダ・試料ホルダ予備排気装置・GATANデジタルマイクログラフソフトウェァを購入し、セットアップを行った。
2. 単結晶フォルステライトの珪素自己拡散係数を圧力3～13GPa、温度1600Kと1800Kで測定じた。単結晶試料の化学組成は、電子線マイクロープローブで調べた限り不純物は検出されない純粋なMg2Si04である。拡散の方向は[100]および[001]である。超高圧高温拡散実験は川井型マルチアンビル装置で行い、拡散プロファイル測定は二次イオン質量分析計で行った。得られた拡散係数は、1600Kでは10^<-20>～10^<-21>m^2s^<-1>、1800Kでは10^<-19>m^2s^<-1>であった。これにより、活性化エネルギーは430kJ/mol、活性化体積は1.3x10^<-6>m^3/molと見積もった。
今回得られた拡散係数は1気圧下での測定結果より2桁以上拡散係数が大きい。これは圧力効果では説明できない。他の研究結果と合わせて総合的に検討すると、拡散実験中に圧力媒体から進入してきた水がフォルステライト結晶中に欠陥を作るためと考えられる。無水条件下で拡散実験をするための特別な技術の開発が必要であることがわかった。
3. 単結晶試料によるMgSi03ペロフスカイトの珪素自己拡散実験を行った。拡散実験は、圧力23GPa、温度1870Kと2070Kで行った。単結晶試料によって得られた珪麦自已拡散係数は、他結晶試料によって得られた珪素自己拡散係数と誤差の範囲で一致する。また、有意な結晶方位依存性は見られない事が分かった。
4. MgSi03ペロフスカイトの変形実験用の単結晶試料を合成し、4軸回折計・EDS付SEMによって結晶性・化学組成・包有物の有無な調べた。単結晶試料は結晶軸方向に垂直な面で研磨した。現在、変形実験用長高圧セルの開発を行っている。
