| Outline of Final Research Achievements |
The equations of state at multi-megabar range of oxide (MgO, Al2O3), silicate (MgSiO3, Mg3Al2Si3O12), and iron alloys (Fe, Fe-Ni, Fe-Ni-S, (Fe,Ni)3S) are established. These equations of state are applicable to the discussion of the internal structure of Super-Earth which has a few times mass of the Earth. Moreover, the double stage micro-paired diamond anvils are newly developed, and it successfully generates over 300 giga-pascal.
