ケイ酸塩・ゲルマン酸塩の圧力誘起非晶質化

抄録

Pressure-induced amorphization is a kinetically hindered phenomenon. The amorphization has been a topic not only in the field of high pressure physics but also in the field of earth science for the last decade. The amorphization of minerals will play an important role to understand the mechanism of deep-forcus earthquakes in the subduction zone, the rheological properties of the slub and the recycling water in the mantle, and so on. In this article, the pressure-induced amorphization of silicates and germanates will be reviewed from the view point of the crystal structures and our resent experiments using the synchrotron radiation will be introduced.
